Color Palette Generator

Creating a color palette with our tool takes seconds.

1. 1

   Choose a base color or leave the field empty. If you already have a brand color, hex code, or color in mind, paste it into the base color field. The generator will build a palette that harmonizes with your chosen color. If you leave the field empty, the tool will generate a fully random palette with no starting constraint.

2. 2

   Select your palette type. Choose from Random, Monochrome, Analogous, or Complementary. Each type uses a different color theory principle to build the palette. The section below explains each type in detail.

3. 3

   Click "Generate Palette." Your color palette appears instantly with swatches showing each color in the set. Each color is displayed with its hex code so you can copy and use it immediately.

4. 4

   Copy the hex codes. Click any color swatch or hex value to copy it to your clipboard, then paste it directly into your design tool, code editor, or style sheet.

That is the entire workflow. No login required, no export limits, and no paywalls.

A color palette is a curated set of colors intended to be used together in a design. A well-chosen palette creates visual harmony, communicates a mood or brand personality, and makes a design feel cohesive rather than random.

In design, palettes typically consist of three to six colors. These usually include a dominant color that sets the overall tone, one or two accent colors that create contrast and draw attention to key elements, and a neutral color used for backgrounds, text, and spacing.

Color palettes are used in virtually every area of visual design including websites, mobile apps, logos, brand identities, marketing materials, illustrations, interior design, fashion, and photography.

The difference between a design that feels professionally polished and one that feels visually chaotic often comes down entirely to color palette selection. Colors that are chosen without a systematic approach tend to clash or feel flat. Colors chosen using color theory principles tend to feel natural and intentional even to viewers who have no design training.

Thetoolity's color palette generator supports four palette types, each based on a different principle from color theory. Understanding these types helps you choose the right one for your project.

Random Palette

A random palette selects colors without any relationship to each other or to a base color. Every color in the set is independently generated, which can produce unexpected and striking combinations that would be hard to discover intentionally.

Random palettes are great for creative exploration when you do not have a specific color direction in mind, for inspiration when you are stuck on a design, and for projects that call for an unconventional or eclectic aesthetic. They are also excellent for quickly generating a variety of options to evaluate before committing to a direction.

Monochrome Palette

A monochrome palette takes a single hue and produces variations by adjusting its lightness, darkness, and saturation. The result is a family of colors that all share the same underlying hue, ranging from very light tints to very dark shades.

Monochrome palettes create a sense of elegance, simplicity, and sophistication. They are easy to apply because every color in the palette is guaranteed to harmonize with every other. They work especially well for minimalist designs, corporate or professional brand identities, and any context where a clean, unified look is more important than visual excitement.

A common mistake with monochrome palettes is choosing colors that are too similar in lightness, which can make a design look flat. The most effective monochrome palettes include a wide range of values, from near-white tints at one end to near-black shades at the other.

Analogous Palette

An analogous palette selects colors that are adjacent to each other on the color wheel. If your base color is blue, an analogous palette would include blue-green and blue-violet alongside the base blue.

Analogous palettes are found throughout nature, which is why they feel so visually comfortable and pleasing. Think of a sunset that moves from orange to pink to violet, or a forest with multiple shades of green and yellow-green. These natural color progressions feel peaceful and harmonious because they avoid high contrast.

Analogous palettes work well for designs that need to feel calm, inviting, or natural: healthcare and wellness brands, environmental and sustainability themes, lifestyle and hospitality designs, and any project where the goal is to put the viewer at ease rather than excite or energize them.

Complementary Palette

A complementary palette pairs colors that are directly opposite each other on the color wheel. Classic complementary pairs include blue and orange, red and green, and yellow and violet.

Complementary colors create the highest possible contrast when placed next to each other, which makes them vibrant, energetic, and visually striking. This high contrast makes them excellent for drawing attention to important elements, creating visual impact, and designing interfaces where clarity and action orientation matter.

Used at full saturation and in large equal amounts, complementary colors can feel overwhelming or even cause visual vibration. The most effective complementary palettes use one color as a dominant and the complementary color as a smaller accent, or they soften one or both colors with tints and shades to reduce the intensity.

Complementary palettes appear frequently in sports branding, food packaging, calls to action, warning signage, and any context where the goal is to capture attention immediately.

Color theory is the body of knowledge that explains how colors relate to each other and how they are perceived by viewers. Understanding a few core concepts will help you choose and use palettes more effectively.

The Color Wheel

The color wheel is a circular arrangement of colors organized by their relationships. Primary colors (red, yellow, and blue in the traditional model, or red, green, and blue in the digital light model) form the foundation. Secondary colors are produced by mixing adjacent primaries. Tertiary colors are produced by mixing a primary with an adjacent secondary.

The relationships between colors on the wheel are what determine palette types. Colors near each other on the wheel are analogous. Colors across from each other are complementary. Colors equally spaced around the wheel form triadic relationships.

Hue, Saturation, and Lightness

Every color can be described using three properties. Hue is the pure color itself, the specific position on the color wheel. Saturation is how vivid or muted the color is. A fully saturated color is pure and intense. A desaturated color moves toward gray. Lightness (or value) describes how light or dark a color is. Adding white produces a tint. Adding black produces a shade. Adding gray produces a tone.

Understanding these three dimensions allows you to create sophisticated palettes that go beyond simply picking colors from the wheel. The most nuanced palettes adjust all three properties across the color set to create balance.

Contrast and Accessibility

Contrast refers to the difference in lightness between two colors placed side by side. Sufficient contrast between text and its background is essential for readability and accessibility. The Web Content Accessibility Guidelines (WCAG) define minimum contrast ratios for text to be readable by people with visual impairments. A contrast ratio of at least 4.5 to 1 is required for normal text, and 3 to 1 for large text.

When building a palette for a web project or app, always check that your foreground and background color combinations meet accessibility contrast requirements. A palette that looks beautiful on a designer's screen may fail accessibility standards if the colors are too similar in lightness.

Choosing the right palette depends on the project type, the audience, the intended mood, and the brand context. Here is a practical framework for making good color decisions.

Start with the emotion or message you want the design to communicate. Colors carry strong psychological associations. Blues and greens tend to communicate calm, trust, and stability, which is why they appear so frequently in financial services, healthcare, and technology brands. Reds and oranges communicate energy, urgency, warmth, and appetite, which explains their prevalence in food brands, sale announcements, and sports. Yellows communicate optimism and attention. Purples communicate luxury and creativity. Neutrals like black, white, and gray communicate sophistication and timelessness.

Consider your audience. Color associations are partly cultural and partly universal. What reads as prestigious in one culture may carry different meanings in another. For global audiences, research the cultural meanings of your chosen colors in your target markets.

Establish a color role for each color in your palette before applying it. Decide which color is the primary background color, which is the primary text color, which is the main brand accent, and which is used for calls to action and interactive elements. Having clear roles prevents palettes from being applied inconsistently across a design.

Test your palette in context before finalizing it. Colors look different when they are next to each other than when viewed in isolation. A color that looks perfect on its own may clash with another in the palette, or it may disappear when placed on a background of a similar lightness.

Once you have generated a palette you are happy with, here are the most common places to apply it across a project.

In web design and development, copy the hex codes into your CSS custom properties or design system tokens. Define each color by its role rather than its value, for example naming a variable "color-primary" rather than "color-blue," so that the palette can be updated globally without changing individual component styles.

In Figma, Sketch, or Adobe XD, create a color style or color variable for each palette color. This makes the palette available from the design tool's color picker across every component and frame in your project.

In WordPress or other content management systems, paste your hex codes into the theme customizer's color settings to apply them site-wide.

In presentations and slide decks, use your palette colors for slide backgrounds, heading colors, accent shapes, and chart colors to create a visually consistent set that looks professionally designed.

In print materials like business cards, flyers, posters, and brochures, use your hex codes to find the closest Pantone or CMYK equivalents for accurate print reproduction. Hex codes are specifically for screen display and need to be converted for professional print work.

In social media graphics, applying a consistent palette across all branded content makes a social media presence look cohesive and recognizable even when different content types are posted.

Different design contexts call for different palette strategies. Here is guidance on common situations designers encounter.

Website and App Color Palettes

A functional web or app palette typically needs five to seven defined colors: a primary background, a secondary background for cards and panels, a primary text color, a secondary text color for captions and labels, a primary brand or accent color for links and interactive elements, a call-to-action color (which may be the same as the accent or a complementary contrast), and a success, warning, and error state color set for form feedback and alerts.

Brand Identity Palettes

Brand palettes usually consist of one to three primary brand colors that appear consistently across all materials, plus a set of secondary and neutral colors that provide flexibility for different applications. Brand color palettes must work across a wide range of contexts: digital screens, printed materials, signage, merchandise, and physical environments.

Illustration and Art Palettes

Illustrators often work with limited palettes of four to eight colors to give their work a cohesive visual style. Limiting the palette forces creative decisions about how colors are reused and layered, which typically produces more interesting results than using unlimited colors.

Interior and Environmental Palettes

Color choices for physical spaces follow different rules than digital design because of how light interacts with paint, fabric, and materials. Colors that look good on screen may look very different on walls under natural and artificial light. Environmental palettes also tend to be dominated by neutrals with accent colors used sparingly for visual interest.
