Confusion Lines

These lines are drawn on top of a Chromaticity Diagram to indicate the Colors of Confusion for a certain type of CVD (typically Dichromacy).

For Dichromats, all colors along a single line should be Colors of Confusion. However, the colors must usually be adjusted for differences in brightness for them to be confused by a Dichromat. Anomalous Trichromats will generally confuse colors that are close together on the same line.

Also Isochromatic Lines.
