Color and Design Tools Complete Guide
Color theory, palettes, CSS generators, and contrast checks — short map of what each tool is for.
Overview
Pick colors, build palettes, generate CSS (shadows, gradients, glass), and check contrast. Start with theory if you need relationships; jump to generators if you already know the look.
Color theory
- Wheel: complementary (opposite), analogous (neighbors), triadic (even spacing). Color wheel.
- Harmony: mono, complementary, split-comp, triadic. Harmony visualizer.
- Models: RGB/HEX for screens, HSL for tweaking, CMYK for print. Color picker converts.
- Mood: associations vary by culture; treat psychology lists as starting points. Emotive palettes.
Palettes
- Generate: palette generator, pastels, mono.
- From images: extract, brand extractor.
- Systems: Material, Tailwind, flat UI pickers; dark-mode builder for low-luminance sets.
A small palette (a few roles: bg, text, accent, border) beats a rainbow you never reuse.
CSS generators
- Shadows/borders: box shadow, text shadow, radius, gradient borders.
- Fills: gradients, noise, SVG patterns.
- Looks: glass, neumorphism, clip-path.
- Motion: animation generator, previewer.
Image and transform effects
Accessibility
- WCAG AA: about 4.5:1 for normal text, 3:1 for large. AAA is stricter. Contrast checker.
- Color vision: simulator — do not rely on hue alone for meaning.
- Pairs: accessible combinations, heatmap.
- Feedback colors (error/success) still need contrast. Feedback tester.
Typography
- Font size, pairing, scale.
- Fluid type (clamp), baseline grid.
Practices
- Store colors as tokens (CSS variables) so themes stay consistent.
- Check contrast on real UI, not just swatches.
- Prefer transform/opacity for motion; go light on stacked shadows.
- Preview dark and light if you ship both.
