The "no change" hash overlay used a single black-or-white stripe color picked by the base luminance, so the perceived average of an unset cell was uniformly biased toward black or white instead of sitting on the actual base color. That made dark base cells look darker than they really are on the keyboard, and light ones lighter. Draw two interleaved stripe sets at base ± offset (per channel), spaced by half-period so the dark and light stripes alternate evenly across the cell. Equal coverage of the two stripe colors keeps the perceived average at base. When a channel is too close to 0 or 1 to fit the full offset (±0.22), halve the offset on the constrained side. The cell's average then drifts at the limits but stays centered on base everywhere else — verified visually across mid-tones, primaries, and near-black/white bases. The "no zone base color known" path keeps the previous neutral-grey look unchanged; the average-preservation property only applies when there is a base color to preserve. |
