From: Hue shifts produced by temporal asymmetries in chromatic signals depend on the alignment of the first and second harmonics Journal of Vision. 2017;17(9):3. doi:10.1167/17.9.3 Figure Legend: Rectangular-wave duty cycles (%) for AS that matched the appearance of the first- and second-harmonic two-component waveforms as a function of the phase of the second harmonic (degrees). The left-hand column shows matches for L-cone-modulated waveforms (red diamonds) and the right-hand columns matches for M-cone-modulated waveforms (green diamonds) for fundamental frequencies from 4 Hz (top panels) to 13.3 Hz (bottom panels). Error bars are ±1 standard error of the mean. The solid lines are single periods of a sinusoid that best fits the L-cone (red lines) or M-cone (green line) matches. The best-fitting sinusoidal mean is plotted in each panel as the dashed horizontal line and noted in bold numerals. The best-fitting sinusoidal amplitude is noted in italic numerals. The icons above the panels highlight the rapid-on, peaks-align, rapid-off, and troughs-align waveforms at 0°, 90°, 180°, and 270°, respectively.
