AccessibleColors
AccessibleColors adds the WCAG accessibility layer the Wolfram Language does not ship: contrast ratios, conformance levels, and contrast-driven color choices. It builds on the built-in color primitives (
ColorConvert
,
Blend
) and works with any color the language understands, including named color
Entity
values, the curated
StandardRed
,
StandardBlue
, … palette, and
LightDarkSwitched
colors for light/dark adaptive interfaces. It is the contrast-checking companion to the broader
Accessibility
features.
WCAGContrastRatio
— the WCAG 2.x contrast ratio between two colors, from 1 to 21
WCAGLevel
— the conformance level (
"AAA"
or
"AA"
, else
Missing
) of a color pair
AccessibleTextColor
— the most legible text color for a given background
AdjustForContrast
— nudges a foreground color until it meets a target contrast
