Maurice most usually thought of color in how it related to value. ( The relative lightness or darkness of a color.) Always making sure that a composition worked in black and white FIRST before moving on into something more colorful.
Cartoon Colour cel vinyl was Maurice's paint of choice. The paints were marked with a one (1) for the lightest value, and the bigger the number, the darker the paint.
GRAY SCALE SHOWING CORRESPONDING COLOR VALUES
The color number appears vertically under each color and #20 represents the darkest value. The gray values on the left are in the same order, from dark to light, and any color number appearing on a horizontal line with a gray value has that same gray value when photographed in black and white.
How is this useful? It's sometimes difficult to tell how dark or light a color really is. When transferring a black and white sketch Maurice wanted to be sure that his colors were as close as possible to the original sketch values.
