Match distances use ΔE′ CAM16-UCS: lower values mean closer digital swatches. These values are not interchangeable with CIE76 or CIEDE2000 and do not guarantee a physical paint match. LRV is estimated from the digital sRGB swatch, not a manufacturer measurement of physical paint.

Paint colors are digital approximations; actual paint and lighting may differ.

Simulations are approximations: color vision varies from person to person, and screens and lighting change how colors look. Rod vision shows lightness as people with complete achromatopsia see it: reds look darker and blue-greens lighter. Red-green figures are for people of Northern European descent; rates vary with ancestry.

How the checker works

Large text: at least 18 pt, or 14 pt bold. Ratios are rounded for display; pass/fail uses the full value.

Adjusts OkLCh lightness with hue and chroma fixed before sRGB clipping and rounding. The suggested hex is checked again.

Simulated CIE76 ΔE below 10 triggers a conservative warning. This is an approximation, not a WCAG requirement; never rely on color alone.

Color Space Conversions

Input: opaque 8-bit sRGB; CIE 1931 2° observer. XYZ and CIELab/LCh use D65 unless marked D50; D50 conversions use Bradford adaptation. XYZ white is Y = 100, or Y = 1 for CSS and u′v′Y. Displayed coordinates are rounded.

Match distances use ΔE′ CAM16-UCS: lower values mean closer digital swatches. These values are not interchangeable with CIE76 or CIEDE2000 and do not guarantee a physical paint match.

Y′CbCr values are normalized coordinates or unquantized 10-bit limited-range code values.

CIECAM02 and CAM02-UCS: D65; L_A = 40 cd/m²; Y_b = 20 (Y_w = 100); F = 1, c = 0.69, N_c = 1.

CAM16 and CAM16-UCS: D65; L_A = 40 cd/m²; Y_b = 20 (Y_w = 100); average surround (F = 1, c = 0.69, N_c = 1).

HCT (Material Color Utilities): D65; L_A ≈ 11.73 cd/m²; Y_b = 18.42 (Y_w = 100); F = 1, c = 0.69, N_c = 1; T = L*.

JzAzBz and JzCzHz use white at 1 cd/m². This luminance convention is separate from the BT.2100 preset.

ACES values use a colorimetric conversion with Bradford adaptation; they do not reconstruct scene exposure.

BT.2100 PQ/HLG and ICtCp assume sRGB white at 203 cd/m². HLG: peak 1000 cd/m², black 0 cd/m², system gamma 1.2, reference surround.
