Dichromatic phenotypes are designated d543, d556, or d563 depending on the maximal absorption of the L/M photopigment (543, 556 or 563 nm); trichromatic phenotypes are designated Δ7, Δ13 and Δ20 indicating narrow (7 nm), medium (13 nm) and wide (20 nm) separation between their medium to long-wavelength photopigments. Embolded lines are subtotals.
