Isoluminant stimuli used in Experiment 2. Left columns: sample mask stimuli. Brown noise (1/f2) and Pink noise (1/f), both filtered with orientation Bandpass (8° fwhh). Right column: sample target stimuli. Gabor patches, oriented like the masks. Top row: Blue–Yellow color axis. Bottom row: Red–Green color axis. Note that visibility of the small illustration of stimuli may be compromised because of low-pass human chromatic contrast sensitivity54. The reader may improve visibility by increasing display size and/or moving closer to the display. Size of stimuli in the experiment was sufficient for them to be clearly visible.
