Read from the package source without running it. The installed server may list more.

• checkContrast

  Check whether a foreground color is legible on a background color per WCAG 2.x contrast ratios. Returns the ratio (1-21) and whether it passes AA and AAA. Set large=true for text >=18pt (or 14pt bold). This is the legibility axis, separate from color-blindness.

• checkImage

  Check whether the colors in an image, chart, screenshot or mockup stay distinguishable for people with color-vision deficiency. Extracts the image's dominant colors, simulates protanopia, deuteranopia and tritanopia, and flags the color pairs that collapse into each other — each with how much of the image's area those colors cover, so a conflict between two large regions ranks above one between tw

• checkPalette

  Check whether a set of colors stays distinguishable for people with color-vision deficiency (colorblindness). Simulates protanopia, deuteranopia and tritanopia and flags the pairs whose perceptual difference collapses under simulation. A screening aid, not a legal accessibility (ADA/WCAG) audit.

• fixPalette

  Take a set of colors that fails the colorblind-safety check and return an adjusted set that passes, staying as close to the originals as possible. Conflicting colors are separated in lightness (the axis color-vision deficiency preserves). Returns the new colors, how far each moved, and whether it fully passes.

• generateSafePalette

  Return N colorblind-safe hex colors — distinct to each other under protanopia, deuteranopia and tritanopia. Seeded with the Okabe-Ito palette and safely extended above eight. Use when asked for accessible / colorblind-safe / colorblind-friendly colors for a chart, plot, map or UI. Never returns an unsafe color.

• simulateColor

  Return how a single hex color appears to someone with a given type of color blindness (protan, deutan, or tritan).
