Does it understand every SVG layer?

No. It compares detected hex colors rather than fully resolving visual stacking.

Does it check rgb colors?

The first version extracts many color formats, but contrast math currently runs on hex colors.

No. It reports low-contrast pairs so you can adjust colors.

Is SVG Color Contrast Checker free?

Yes. SVGKit tools are free to use with no account required.

Does SVG Color Contrast Checker upload my files?

No. The tool runs entirely in your browser, so your files never leave your device.

Which standards does it check against?

The SVG specification plus the specific rules this tool focuses on. Findings reference the rule so you can judge each one.

Does it fix problems automatically?

No. Validation reports findings; the edit and optimize tools apply the fixes.

Can it produce false positives?

Rarely. When a finding does not apply to your context, note it and move on — the tool cannot see how the SVG is consumed.

Contrast model

The checker extracts hex colors and compares pairs using relative luminance, reporting pairs below a 4.5:1 AA-style threshold.

Limitations

SVG layering can be complex. Treat this as a fast color audit, then verify actual foreground/background relationships visually.

SVG Color Contrast Checker reports findings with severity and context — fix hard failures first, then re-run for a clean report.

What gets checked

SVG Color Contrast Checker parses the document locally and validates it against structural rules and this tool's focus area, reporting each finding with enough context to locate it.

Common findings and fixes

Typical issues include missing viewBox attributes, duplicate IDs, unsafe active content, and deprecated structures. Most have a direct fix in the matching edit or optimize tools.

Severity and manual review

Parse errors and unsafe content are hard failures; style-level findings need judgment based on where the SVG ships. Automated checks complement, not replace, a visual review.

Privacy

Validation runs locally in your browser. Files are parsed in the page and never uploaded.

How to use

Paste SVG. Paste SVG markup with hex colors.
Review pairs. Check reported low-contrast color combinations.
Adjust colors. Update fills, strokes, or text colors in the source artwork.
