POSTERIZE

→ POSTERIZE

A `tlhotlha` value: cut down the number of colours used.

tlhotlha(POSTERIZE, count)

A second number is how many colours to keep in each part: tlhotlha(POSTERIZE, 4) keeps four reds, four greens and four blues.

It does not change colours already at the extremes. Measured: a pure red dot [255, 0, 0] is unchanged even at POSTERIZE, 2, because 255 and 0 are the extreme values. What changes is the colours in between: [140, 115, 0] becomes [170, 85, 0] at four.

The name stays English. Posterize is a term from old poster printing, and no Setswana word for it exists in any source searched — the route hue and millis took. This page is where the explanation lives.
