Oklch Link Colour Ranges — APCA

Each cell shows the Oklch L×C plane for that hue (C increases →, L increases ↑). Bright pixels pass the background threshold and are distinguishable from the regular text colour (|Lc| ≥ 15 vs #000 for light, #ccc for dark); dimmed pixels are in-gamut but fail one or both checks; checkerboard = out of sRGB gamut. Ranges below each canvas are the 10th–90th percentile of passing (L, C) pairs.
