This is an attempt at improving the experience of users with color vision impairement. At this time this feature can only be enabled for debugging: adb shell service call SurfaceFlinger 1014 i32 PARAM with PARAM: 0 : disabled 1 : protanomaly/protanopia simulation 2 : deuteranomaly/deuteranopia simulation 3 : tritanopia/tritanomaly simulation 11, 12, 13: same as above w/ attempted correction/enhancement The enhancement algorithm tries to spread the "error" such that tones that would otherwise appear similar can be distinguished.
