Tools (18)
| Name | Description | Schema |
|---|---|---|
parse_color | Read any color and describe it: HEX, RGB, HSL and OKLCH values, the closest human name, the closest Tailwind class, its hue family, whether it fits sRGB and Display P3, and which text color, white or | typed |
convert_color | Convert a color between formats: hex, rgb, hsl, hsv, hwb, cmyk, lab, lch, oklab, oklch, display-p3, rec2020, xyz and platform code (swiftui, uikit, flutter, android). Values follow CSS Color 4. | typed |
find_colors | Search color names by words, like "sage", "dusty rose", "midnight blue" or "бордовый", and get their HEX values. Searches common names in English and Russian and about 30 000 extended color names. Use | typed |
check_contrast | Check text contrast against a background with both WCAG 2 (ratio, AA and AAA for normal and large text) and APCA (Lc value and the usage level it allows). Also suggests the nearest text color that pas | typed |
fix_contrast | Find the closest color that reaches a contrast target by changing only OKLCH lightness, so the hue and character stay. Targets: aa (4.5:1), aa-large (3:1), aaa (7:1), apca-body (Lc 75), apca-content ( | typed |
audit_palette | Check every text and background pair in a palette with WCAG 2 and APCA, list which pairs are safe for body text, large text or only decoration, find colors that people with color blindness cannot tell | typed |
check_gamut | Check whether a color fits the sRGB, Display P3 and Rec. 2020 gamuts, and get the closest sRGB fallback that keeps lightness and hue (CSS Color 4 gamut mapping in OKLCH). | typed |
nearest_names | Find the closest named colors, CSS color keywords and Tailwind CSS classes for a color, ranked by perceptual distance (deltaE OK). | typed |
compare_colors | Compare two colors: CIEDE2000 and deltaE OK difference with a plain verdict (identical, nearly, similar, different, opposite), lightness shift in percent, chroma and hue shift, and the contrast betwee | typed |
generate_scale | Build an 11-step tint and shade scale (50, 100 … 900, 950) from one color in OKLCH, the same shape as Tailwind palettes, with even perceived lightness steps. | typed |
tints_shades | Get tints (mixed with white), shades (mixed with black) and tones (mixed with gray) of a color, evenly spaced, as HEX. Good for hover states, borders and backgrounds. | typed |
harmonies | Get color harmonies for a base color, computed in OKLCH so lightness stays even: complementary, split-complementary, analogous, triadic, tetradic, square and monochromatic. | typed |
mix_colors | Mix two colors at a ratio in a chosen color space, like CSS color-mix(). OKLab keeps the middle bright, sRGB tends to turn gray. Returns the result and a ready color-mix() expression. | typed |
make_gradient | Build a CSS gradient from 2 or more colors with interpolation in OKLab, OKLCH or sRGB. Returns modern CSS with the color space, a fallback with precomputed stops for older browsers, and the stop color | typed |
generate_palette | Generate a harmonious palette in OKLCH. Keep colors you already have, pick a style (auto, analogous, complementary, triadic, monochromatic, pastel, vivid, muted, dark) and pass a seed to get the same | typed |
simulate_cvd | Show how colors look with protanopia, deuteranopia, tritanopia and achromatopsia (Machado 2009 at full severity), and list the pairs that become hard to tell apart. | typed |
export_tokens | Turn a list of colors into ready code: CSS custom properties, a Tailwind v4 @theme block, SCSS variables, JSON, W3C design tokens (DTCG), a JavaScript array or an SVG swatch strip. Unnamed colors get | typed |
build_system | Build a full color system from a brand color: 50–950 scales for primary, secondary, accent, neutral and status colors, light and dark theme roles, exported as a Tailwind v4 theme, CSS variables, shadc | typed |
