Could this be used by colorblind people to remap hues? Like for red apples on a green tree, you could remap red to orange.
Windows has built-in color filters already but to my knowledge it does not allow to customize them, though. Open this in the run dialog (Win+R) to directly open to the appropriate settings page: ms-settings:easeofaccess-colorfilter
