Equiluminant conditions defined by the OMR. a Experimental setup. Spinning sunray-shaped stripes projected onto the display at the bottom were reflected horizontally into rotating vertical stripes by a polyvinyl-chloride mirror. b Normalized spectra from the display (MB16AP; Asus) used in (c–h). White (RGB values of 255/255/255), red (255/0/0), green (0/255/0), and blue (0/0/255) light were measured at every 1 nm using a Spectromaster C-7000 (Sekonic) and are shown in gray, red, green, and blue, respectively. c OMR in gray–gray stripes. One gray was fixed at 128/128/128, and the other was set at either 0/0/0, 50/50/50, 80/80/80, 90/90/90, 100/100/100, 110/110/110, 120/120/120, 130/130/130, 140/140/140, 150/150/150, 160/160/160, 170/170/170, 200/200/200, or 255/255/255. See Fig. 2c for details. Some data points are beyond the graph area. Black, wild-type fish; blue, sws1/sws2 double mutant. d OMR in red–gray stripes. Red was fixed at 255/0/0, and gray was either 0/0/0, 50/50/50, 80/80/80, 90/90/90, 100/100/100, 110/110/110, 120/120/120, 130/130/130, 140/140/140, 150/150/150, 160/160/160, 170/170/170, 200/200/200, or 255/255/255. e OMR in green–gray stripes. Green was fixed at 0/255/0, and gray was either 0/0/0, 50/50/50, 100/100/100, 140/140/140, 150/150/150, 160/160/160, 170/170/170, 180/180/180, 190/190/190, 200/200/200, 210/210/210, 220/220/220, 230/230/230, 240/240/240, or 255/255/255. f OMR in blue–gray stripes. Blue was fixed at 0/0/255, and gray was either 0/0/0, 50/50/50, 60/60/60, 70/70/70, 80/80/80, 90/90/90, 100/100/100, 110/110/110, 120/120/120, 130/130/130, 140/140/140, 150/150/150, 200/200/200, or 255/255/255. g OMR in blue–red stripes. Blue was fixed at 0/0/255, and red was either 0/0/0, 50/0/0, 100/0/0, 110/0/0, 120/0/0, 130/0/0, 140/0/0, 150/0/0, 160/0/0, 170/0/0, 180/0/0, 190/0/0, 200/0/0, or 255/0/0. h OMR in dark-blue–red stripes. Dark blue was fixed at 0/0/160, and red was either 0/0/0, 50/0/0, 80/0/0, 90/0/0, 100/0/0, 110/0/0, 120/0/0, 130/0/0, 140/0/0, 150/0/0, 160/0/0, 170/0/0, 180/0/0, 190/0/0, 200/0/0, or 255/0/0
