### Notes

The upper panel shows the spectrum locus (continuous line) andselected wavelengths (yellow circles) plotted in the Stockman & Sharpe (2000) 2-deg *l,m *cone
chromaticity space. The L- (red diamond), M- (green circle), and S- (blue square) cone fundamentals plot at (1,0), (0,1), and (0,0),respectively. The lower panel shows thw spectrum locus (continuous line) and selected wavelengths (filled circles) plotted in the Stockman & Sharpe (2002) 2-deg LMS cone excitation space, and the L- (red line),
M- (green line), and S- (blue line) cone vectors.
