Colour matching scale display has base circle of colour shades arranged in a circle with set spacings between them

摘要

The colour scale has a base grey (SG) on which a colour disc is printed. The colour shade circle (HC) extends outwardly. The number of colours in the colour circle is limited. The colours are arranged around the circle. A mixing of three or a multiple of three colours with a similar spacing in the circle provides a similar shade from the base grey.
