Another inspiration from @AkiyoshiKitaoka! Color completion illusions similar to the Sohmiya illusion can be created with straight lines rather than waves. For example, here are blue and green lines that produce a yellowish illusory color between the green lines. More to come.pic.twitter.com/E5iJKRJwDj
Amazingly, a yellowish illusory color also comes from red lines in place of the green lines. As I will try to show in the next few days, almost all color-completion illusions of this sort tend to produce yellowish illusory colors. Producing other colors, e.g., blueish, is hard.pic.twitter.com/NuElPVRFej
