Text and background contrast
Normal text needs 4.5:1. Large text needs 3:1.
A different color is not always a readable color.
Presets use the RGB/HSL wheel. Analogous 5 explores nearby hues; Tonal 5 adds shades and tints; Balanced 5 is our own mix of related hues, opposite accents, and a pale tint. Custom 5 lets you edit each color independently. Imported palettes keep their original colors and roles until you edit them. The bright wheel shows hue and saturation; result colors include brightness. Colors can share a wheel position. Palette suggestions do not guarantee readable text.
Contrast is calculated from the final, opaque sRGB HEX colors. AA text needs 4.5:1; AA large text needs 3:1; AAA normal text needs 7:1. Large text means at least 24 CSS px, or about 18.7 CSS px when bold. Ratios are displayed to two decimal places without rounding up; pass/fail uses the full calculation. Transparency, images, and gradients need their own checks.
