- Most pigments contain a metal as to which a color or color range is often associated
- Iron = red – yellow
- Chromium = red – yellow
- Copper = blue – green
- Cobalt = yellow – violet (depending on co-metals)
- Most metals involved in pigments are transition metals
- Color is exhibited by the d-block portion of periodic table with partly filled d subshell
- Color occurs by the absorption of photons of light and reflection of only certain wavelengths
