Ever wondered why everyone keeps going on about the beautiful colors of the sunset? Having trouble seeing if a tomato is ripe? What about bananas? Or maybe you just find the world to colorful and want to keep it a little more black-and-white for the day? Achromator translates all color from the phone video stream into unique animated textures. It encodes all hues and shades - without loss of information! It even keeps much of the structure found in color, like mixing, gradual blending and complementary hues. The pattern generator can be adjusted to your personal preference - pattern size, speed and selection of individual colors.
