Why Contrast Matters for SVG

SVG icons and text need sufficient contrast against their background to meet WCAG AA (4.5:1 for text, 3:1 for graphics/large text) — check fill and stroke colors against the actual rendered background.

  • WCAG AA: 4.5:1 for text, 3:1 for graphics
  • Check fill/stroke against the real background
  • currentColor inherits context — verify per use

Testing Your Colors

Use a contrast checker tool with your SVG's hex fill values and the background color, especially when using currentColor or CSS variables that change per theme.

  • Test every theme variant separately
  • Pay special attention to currentColor contexts
  • Re-check after any palette or theme update

Frequently Asked Questions

Does an SVG icon need the same contrast ratio as text?

Meaningful graphics generally need at least 3:1 contrast under WCAG, while body text needs 4.5:1 — check your specific use case against the guideline.

How do I check contrast for an SVG using currentColor?

Resolve what currentColor actually renders as in each context (light/dark theme, hover state) and test that specific color against its background.
