Describes something that has been treated or combined with a chemical compound known as bichromate.
The artist used bichromated paper for his watercolor paintings to enhance the colors.
Bichromated → It is formed from "bi-" (meaning two) and "chromate" (from Greek "chroma", meaning color, and the suffix "-ate" indicating a chemical compound). The word "bichromated" refers to a compound containing two chromate ions, thus relating to its color properties.
Think of 'bi-' meaning two, and 'chroma' relating to color — this helps you remember that 'bichromated' involves two color-related compounds.
