Common Pitfalls to Avoid
-
• Testing only text contrast and ignoring form bordersWCAG 2.1 Level AA requires at least 3.0:1 contrast for input borders and interactive UI components.
-
• Using pure saturated green on pure saturated redFails accessibility for color-blind users (deuteranopia/protanopia). Use lightness contrast in addition to hue.
-
• Testing colors only on desktop monitors under dim office lightingAlways test interfaces under bright outdoor sunlight where low contrast causes severe legibility drop.
Pro Tips for Best Results
- Aim for a contrast ratio of at least 4.5:1 on all body typography to pass WCAG AA standards.
- Use relative units (rem/em) rather than fixed pixels for accessible typography scaling.
- If your brand primary color falls slightly below 4.5:1, reserve it for bold headers and use a darkened shade for body copy.
Local Processing Guarantee
Renders in real time within your browser canvas and CSS engine. Zero external tracking.
When to Use
- Generate harmonious secondary and accent colors from a primary brand hex.
- Build high-contrast triadic color schemes for dashboards and charts.
- Create subtle monochromatic shades for UI background layers.
Generating physical industrial spot-color ink formulations (Pantone PMS matching) without calibrated spectrophotometer proofing.
- • Generated outputs conform strictly to W3C WCAG 2.1 & CSS Color Module Level 4 standards. Display or print rendering requires output media or hardware supporting the target color profile and resolution.
- • Local device synthesis guarantees zero server logging, but batch creation of hundreds of files sequentially should be managed in batches to prevent UI throttling.
