CHROMA

Rule 12h. Stains are usually not reduced to below three-fourths chromatic intensity. Nearly gray side walls, however, call for a reduction to one-fourth intensity.

Rule 12i. Wall colors are usually reduced to three-fourths chroma to a minimum reduction of slightly less than one-fourth chroma.

Rule 12j. Ceilings should usually be reduced in chroma to three-fourths intensity, with slightly less than one-fourth chroma as a minimum reduction.
