asked which paints went into the bucket for creating this
particular mid-range "gray". She looked it up and we were both surprised to
find out the mixture required an "orange", a "blue" and "white"!!!
Needless-to-say, we continued with other swatches and types of paint (pearl
finish) until we came up with a mixture of "dark-gray" and "white".
Why should you be so surprised that blue and orange would create neutral
gray? The are opposite the colorwheel from each other in pigments. Just the
two colors should create a near-black. The amount of white will determine the
gray value. Working with oil paints, there really is no such thing as "black"
so we mix Alizaron Crimson and Veridian Green. How else do you make gray? Are
we too effected by our world of light (RGB & CMYK) to have forgotten how we
mixed colors in art class in school?
