According to Gordan Ugarkovic, “This is calibrated color using actual red, green and blue filters. If you were to enhance the contrast you’d see there are white-yellow cloud patterns. The problem with pretty much all images of Venus released so far is that they’ve been enhanced/false color or just colorizations of ultraviolet frames. It’s only once you go to (ultra)violet wavelengths that any cloud bands become readily visible. Human eye just doesn’t cut it here.”
Thanks as usual to for this rare gem.
