Colour Contrast Analyser
The Colour Contrast Analyser samples colors and compares their contrast with WCAG thresholds, including useful simulations and visual checks.
Limitations: A passing ratio does not prove that text is readable in context. Font size, weight, states, overlays, images, and user settings still require inspection.
Why it is useful
The Colour Contrast Analyser samples colors and compares their contrast with WCAG thresholds, including useful simulations and visual checks. This resource is especially useful for Measuring foreground and background color contrast from the screen. Review the current instructions and limitations from TPGi before relying on it for important work.
