Achromatic

Also called neutral, greyscale, grayscale

This entry has not been translated yet and is shown in English.

Having no hue: black, white, and the greys between, sitting on the central axis of any color solid where chroma is zero. Achromatic work is not colorless work — it isolates value and forces the structure into the open, which is why the greyscale proof remains the fastest test of whether a layout is actually working.

A continuous neutral ramp from black to white above the same ramp in seven steps. Chroma is zero the whole way across both.
