About ColorKit
A practical studio for color tools: palette generation, picker, gradient construction, hex conversion, and contrast checks — built for designers who need a usable answer, not a tutorial.
Why ColorKit exists
Most color-tool sites optimize for a single screenshot rather than for the working designer behind it. You pick a swatch, the page opens five upsell modals before you can copy the hex string, and the export panel wants an account. ColorKit inverts that flow. The tools are small, single-purpose, and copy-first: hex, RGB, HSL, and OKLCH values are visible as text and reproducible from a copied URL.
The tool cluster
The palette generator builds harmonies (analogous, complementary, triadic, split-complementary, square, tetradic) from a seed color and includes a tints-and-shades fan for production work. The color picker offers HEX, RGB, HSL, and OKLCH inputs side by side so a value you grabbed from a screenshot translates into the model your design tokens expect. The gradient studio supports linear and conic gradients with full stop control. The hex/RGB converter handles both 3-digit and 6-digit notation plus alpha channel. Each tool exposes a copy-link button so a teammate can open the exact swatch you are looking at.
Accessibility & color science
Contrast checks use the WCAG 2.1 relative-luminance formula and report AA and AAA thresholds for normal and large text. The OKLCH-aware controls help avoid the perceptual surprises that arise when you scale lightness in sRGB. Where a value depends on a specific gamut (P3, Rec. 2020), the tool notes the gamut in the output panel rather than silently converting.
Privacy & publisher
The palettes you generate, the swatches you paste, and the gradient stops you fine-tune stay on your device. ColorKit is a static site served from a CDN; there is no backend collecting your color choices. The site is published by the inovisum team, a small tools studio. The color-harmony rules and OKLCH conversion math are reviewed each release pass; if you spot a value that disagrees with another reputable color reference, write in.
