About the Color Palette Generator API

Color Palette works by generating color palettes based on color theory principles. It returns harmonious colors with multiple format outputs (HEX, RGB, HSL), accessibility metrics, ready-to-use CSS variables, and downloadable palette images.

What people use it for

Dynamic Theme Generation
White-label SaaS dashboards build branded interface themes instantly by supplying a customer's primary brand HEX to retrieve complementary UI shades and legible text colors.
Website Builder Customization
When site owners select a key accent color, CMS site editors generate matching color sets to style page headers, background sections, and button borders.
E-Commerce Product Showcases
Match catalog item tones to surrounding promotional banners by creating monochromatic or contrasting palettes directly from product hero image colors.
Design Tool Integrations
Digital illustration software presents automated analogic or triadic color swatches to artists based on their current active brush color.

Questions.

Common questions about the Color Palette Generator API.

Read the docs →
Is it cheap enough to generate palettes for every user theme?
Yes. At 2 credits per call, the Starter plan covers 100,000 palette generations a month, which works out to $0.30 per 1,000 calls (about $0.0003 per call). The Free plan includes 100 calls each month at no cost.
Are accessibility metrics and CSS variables included on the Free plan?
No. WCAG contrast compliance data, luminance scores, HSL values, CSS variables, and downloadable palette image URLs require a paid plan starting with Starter. The Free plan returns HEX and RGB values, color names, and readability indicators, and limits palettes to 5 colors.
What color schemes does the generator support?
Color Palette Generator supports monochromatic, contrast, triade, tetrade, and analogic schemes. You can apply color variations on every plan; paid plans let you fine-tune spacing distance across multi-color schemes and add complement colors to analogic palettes.
Does the base color accept hex codes with a leading hash mark?
No. The base color parameter requires a HEX string without the leading hash, such as ff5733 instead of #ff5733. The response then provides the normalized color with the hash prefix, its HSL wheel degree, and the closest color name.
Can I restrict palette colors to web-safe values?
Yes. Setting the webSafe parameter to true restricts all generated colors to standard web-safe values. You can combine this with any supported color scheme and set palette sizes between 1 and 16 colors on paid plans.
