2 Tools

Design Tools cover the visual layer of web development, color palettes, CSS gradients, box shadows, border radius, aspect ratios, and accessibility contrast checking. These tools bridge the gap between design intent and CSS implementation, helping developers ship pixel-perfect, accessible interfaces.

→ Color Contrast Checker
03

Create a CSS gradient with live preview

→ CSS Gradient Generator
04

Simulate how a color palette looks with color vision deficiency

→ Color Blindness Simulator
05

Generate responsive spacing and type scales

→ Spacing Scale Generator

Common Mistakes to Avoid

  • ✗Choosing colors that pass contrast ratio on paper but fail when rendered with subpixel antialiasing on low-DPI screens.
  • ✗Using only WCAG AA (4.5:1) for body text when AAA (7:1) is achievable, AA is the minimum, not the target.
  • ✗Designing gradients in sRGB and shipping without checking how they render in wide-gamut displays, use OKLCH for perceptually uniform gradients.
  • ✗Relying on color alone to convey information, always pair color with text labels or icons for accessibility.

Privacy-First by Design

Design tools process color values and CSS, no sensitive data is involved. All tools run client-side with no network requests.

Frequently Asked Questions

What contrast ratio does WCAG 2.2 require?

Level AA requires 4.5:1 for normal text and 3:1 for large text (18pt+ or 14pt bold). Level AAA requires 7:1 for normal text and 4.5:1 for large text.

What is OKLCH and why should I use it?

OKLCH is a perceptually uniform color space where lightness is consistent across all hues. Unlike HSL, rotating the hue in OKLCH does not change perceived brightness, ideal for design systems.

Can these tools help me build an accessible color palette?

Yes. Use the Color Contrast Checker to verify each foreground/background pair meets WCAG AA or AAA, and the Color Blindness Simulator to test under protanopia, deuteranopia, and tritanopia.
