Abstract
An article includes a substrate with at least first and second materials disposed in or over the substrate. The first material is a non-color changeable material of at least one first color and the second material is a thermochromic color changeable material activated to produce at least one second color different from the first color. Additive color mixing of the first and second colors produces at least one third color different from the first and second colors.
