Color guides and practical tutorials.

Build a balanced, accessible, and reusable color palette with clear roles, practical testing, and a worked example.

Understand WCAG contrast ratios, AA and AAA targets, UI boundaries, worked examples, and a practical testing workflow.

Compare HEX, RGB, HSL, OKLCH, Display P3, alpha, and CMYK planning values with practical use cases and limitations.

Choose the right screen and print workflow, understand gamut differences, ICC profiles, soft proofing, and practical handoff.

Extract, refine, test, and reuse a practical color palette from a photo or screenshot while keeping processing local.

Build a perceptually balanced Tailwind 50–950 color scale with semantic tokens, accessible states, and export examples.

Create an accessible palette with contrast, non-color cues, semantic states, focus visibility, and realistic component testing.

Design layered dark surfaces, readable text, controlled chroma, accessible states, and theme-ready semantic tokens.

Use OKLCH lightness, chroma, and hue to build consistent web palettes, scales, themes, and sRGB fallbacks.

Compare spot colors and CMYK process colors, understand production trade-offs, proofing, and independent CPS planning references.

Understand Delta E 2000, Lab-based color comparison, practical interpretation, tolerances, and Color Pick CPS matching.

Understand CPS numeric codes, 1,386 independent references, families, tones, intensities, matching, exports, and limitations.

Test real button labels, fills, borders, focus rings, icons, and interaction states with a measured WCAG contrast matrix and a repeatable component workflow.

Map raw palette values to stable background, surface, text, action, feedback, focus, and interaction roles for light and dark interfaces.

Use pastel colors as accessible surfaces, accents, and states by pairing them with stable foregrounds, role mapping, OKLCH adjustments, and non-color cues.

Design status, charts, controls, and navigation that remain understandable under common color-vision differences and simulation limits.

Turn one brand color into primitive, semantic, component, light-mode, dark-mode, and high-contrast color tokens without losing traceability.

Compare two color-token releases, detect breaking changes and probable renames, test theme regressions, and create a safer migration plan.

Learn how to turn one brand color or an existing palette into themes, semantic roles, component states, repair evidence, and production-ready design-token exports.

Upload a palette JSON, CSS variables, Tailwind colors, DTCG tokens, or a Color Pick export and turn the detected colors into a structured design system.

Import real chart data, choose categorical, sequential, or diverging colors, model weighted adjacency, inspect the weakest pair, repair weak combinations, add redundant encodings, and export an accessible implementation pack.

Analyze a chart screenshot locally, review likely background and series colors, identify weak pairs, and understand what a pixel-based audit cannot prove.

Import CSV, TSV, JSON records, or pasted tables locally, review inferred fields and midpoint, apply data-derived adjacency, and build an accessible chart system.

Choose direct labels, structured legends, programmatic series associations, chart descriptions, source-data tables, keyboard behavior, and responsive strategies.

Use weighted adjacency, locked series, CIEDE2000 evidence, safe subsets, redundant encodings, and selective repair to fix weak chart-color combinations.

Check monotonic lightness, perceptual step balance, hue drift, midpoint neutrality, symmetry, endpoint balance, and responsive behavior for ordered chart colors.

Learn how to compare color-mix() spaces, compile fallbacks, build relative-color recipes, inspect wide gamut, test browser support, and export a modern CSS color system.

Compare how CSS color-mix() behaves in sRGB, linear sRGB, Oklab, OKLCH, Lab, LCH, HSL, and Display P3, including hue routes and fallback planning.

Build dynamic CSS color relationships with relative color syntax, light-dark(), and contrast-color() while keeping deterministic fallbacks and honest support boundaries.

Audit repeated color literals, near duplicates, legacy rgb and hsl syntax, hard-coded component colors, and opportunities for custom properties and modern derived relationships.
