Use the live tools below. Values are calculated in your browser unless a database-backed match is explicitly requested.
Universal Color Analyzer
Exact Pixel & Palette Lab
Upload an image. Click any pixel for its exact source RGB/HEX value. Dominant palette extraction uses actual sampled image pixels rather than invented rounded colors.
Palette Generator & Variants
Delta-E, LAB & Temperature
Contrast, WCAG & Color Vision
Production Color Tokens
Gradient & Blend Composer
Semantic Roles & Scale Builder
OKLab, OKLCH, XYZ, YIQ & Alpha
Additional modern and legacy color-space inspection using the same source HEX.
Similarity, Name & Family Search
Uses the connected 53,785-color library. Results are database-backed, not fabricated.
Production Color Quality Checks
Run practical checks before using a color system in production UI.
Professional Color Science Lab
Compare ΔE76, ΔE94 and ΔE2000, inspect OKLCH, neutrality, luminance and practical gamut-risk indicators.
Perceptual Palette & Accessibility Matrix
Build an OKLab-interpolated ramp and test every generated color against white and black.
Color-Space Mixing Studio
Compare RGB, HSL, LAB and OKLab interpolation so the same endpoints can be evaluated across spaces.
Contrast Matrix & UI State Lab
Enter a comma-separated palette and generate pairwise WCAG contrast results plus practical UI-role checks.
Brand Identity Color Suite
Generate primary, secondary, accent, neutral, hover and focus candidates from your brand colors.
CMYK & Prepress Helper
Practical CMYK inspection, estimated total ink coverage, grayscale and black-construction guidance.
Production Token Export Studio
Generate CSS, SCSS, Tailwind, SVG and design-token representations from a palette.
Pixel Neighborhood & Histogram Lab
After uploading an image above, select a pixel and inspect its local neighborhood and sampled color distribution.
