A 16 color palette for dichromats and trichromats

Ametameric is as a system palette that provides the standard CGA/ANSI colors accomodating various forms of human color blindness/color vision deficiencies. 16 colors (including white, black and two grays) that all provide sufficient contrast for all common types of color vision. When working as intended, TUIs made to work well with the system colors (rather than 256/true color) should become accesible for color vision deficient users without further tweaks needed.
