Red text on Black bacground: hard to see

Some of these moblie screens are not so bright in the daylight - hard to see. The red text on the black background (modified or highlighted parameters) are sometimes impossible to see, even when trying hard to focus. quick glances are impossible.
is there a setting to change these colors? if not, could i request a change? also, keep in mind that color blind ppl (not me) see red as almost black. blue is the other end of the light frequency spectrum.
