From: Hummingbird plumage color diversity exceeds the known gamut of all other birds
Unusual hummingbird plumage spectra (gray) from Fig. 4 with the total avian color gamut (black) from Stoddard and Prum (2011) a–c plotted in avian VS color space and viewed from three angles: a standard view, b a top-down view, and c a view toward the l-m edge from slightly below. d Robinson projection of the hues of the same color points. All spectra are labeled with the first two letters of the genus and species: Ag-co– Aglaiocercus coelestis coelestis, At-el– Atthis ellioti ellioti, Bo-ja– Boissonneaua jardini, Co-to– Coeligena torquata fulgidigula, He-vi– Heliangelus viola, Kl-gu– Klais guimeti, Me-ph– Metallura phoebe, Me-ty– Metallura tyrianthina smaragdinicollis, Sc-ge– Schistes geoffroyi, Tr-po– Trochilus polytmus, and Ur-be–Urosticte benjamini.
