Understand
Inspect HEX, RGB, HSL, HSV, HWB, CMYK, LAB, luminance and modern color representations before making a design decision.

WHY COLOR LAB
One place for the decisions that happen between a color value and a finished design.
Color work often crosses several applications and disconnected calculators. Color Lab is designed around that real workflow: inspect a color, understand it, compare it, engineer a palette, validate it, and export it.
Compare
Use perceptual similarity and CIEDE2000 workflows to understand which colors are actually close rather than relying only on visual guessing.
Engineer
Create harmonies, tints, tones, shades, data palettes, UI states, brand variants and token-ready color systems.
Validate
Check contrast, luminance, color-vision simulations, image samples and production-oriented color constraints before publishing.
LIVE COLOR ENGINEHEX → LAB → ΔE → WCAGOne connected workflow
THE ENGINE
Built as a color workbench, not just a collection of calculators.
The platform combines a Node.js/Express application layer with MySQL-backed color intelligence and browser-based interactive tools. This lets live database-backed search and analysis sit beside instant client-side workflows.
- Perceptual analysisCIEDE2000 similarity and color-space inspection.
- Accessibility engineeringWCAG contrast, luminance and color-vision workflows.
- Image intelligenceExact pixel sampling and image-derived palette workflows.
- Production exportsCSS, tokens, SCSS, Tailwind, Flutter, React Native and SVG-oriented outputs.
COLOR DOMAINS
Designed around the full color lifecycle.
From the first sampled pixel to the final design token, the platform keeps color at the center.
Color Science
LAB, XYZ, OKLab, OKLCH, perceptual difference, hue and chroma analysis.
Palette Engineering
Monochromatic, analogous, complementary, triadic, tetradic and advanced harmony systems.
Image Intelligence
Exact pixel extraction, dominant colors, frequency analysis and image-to-library matching.
Accessibility
Contrast targets, text roles, UI states, focus rings and color-vision simulation.
Brand Systems
Core colors, neutrals, gradients, hover states, logo backgrounds and brand tokens.
Prepress
CMYK inspection, ink coverage helpers, grayscale and web-to-print checks.
Developer Workflows
CSS variables, modern CSS color functions, SCSS, Tailwind and application tokens.
Data Visualization
Sequential, diverging, categorical, heatmap and scientific palette generation.
OUR PRODUCT PRINCIPLES
Useful first. Clear always. Flexible by design.
PracticalOutputs are intended to be usable in real design and development workflows.
TransparentDatabase-backed color intelligence and calculated results are kept conceptually distinct.
AccessibleResponsive interfaces and accessibility-oriented tools are treated as first-class workflows.
ExtensibleThe Node.js architecture allows new color workflows to be added without discarding the existing platform.
