Unlimited Color Studio

Unlimited Color Studio is a complete color workbench for designers, developers, and anyone who needs to pick, build, and validate color with precision. Every tool reads and writes one shared studio session: a working color, working pair, and working palette that follow you from tool to tool. Capture. Pick, sample, search, and normalize color sources. Eyedropper picks colors from the screen and branches them into your session. Image Sampling extracts palettes and probes regions to build style biased palettes from photos. Named Colors gives you named references with nearest name lookup. Palette Scales lets you browse scientific and UI friendly scales and sample them into your session. Palette Collection offers curated palettes by category, including nature, modern, vintage, and bold. Build. Convert, generate, branch, mix, and theme color systems. Conversion Lab edits one color in any space and inspects it everywhere. Palette Lab generates, scales, randomizes, and constrains palettes around a working palette. Color Mixer blends colors numerically and compares perceptual versus spectral results. Gradient Studio builds and exports gradients from your working swatches. Experiment Board pins swatches, branches variants, and saves board snapshots. Theme Studio browses shipped themes, builds role based palettes, and audits them against your session. Validate. Compare, audit, simulate, and inspect perceptual failures. Compare Lab measures Delta E, contrast, APCA, and perceptual difference between two colors. Contrast Checker checks WCAG AA/AAA and APCA ratios between foreground and background colors. Color Blindness simulates color vision deficiencies to confirm your colors stay distinguishable. Gamut Navigator explores wide gamut behavior across supported color spaces. Palette Doctor audits a whole palette for contrast and color vision collisions and names the pair that fails. Play. Sharpen your eye with built in training modes. Color Match, Name That Color, What's My JND, Contrast Rescue, Ramp Repair, Gamut Guess, and Temperature Match turn color theory into fast, focused practice. Vision. See how seeing works. Cone Response plots the eye's three cone sensitivities. Imaginary Primaries shows why no real light can match every color. Metamers builds two spectra that look identical. Illuminant Lab relights a scene under daylight and tungsten. Temperature inspects black body color and Kelvin mappings. Rod Vision shows the shift to night sight. Rainbow traverses the visible spectrum and sends stops straight to your palette. Your studio session lives in a persistent sidebar with recents, favorites, and snapshots, so nothing you pick or build ever gets lost between tools.
