#28 Colour blindness discrimination problem


Due to colour blindness, my son cannot use the simulator, or at least he cannot use the breadboard module because he cannot see the difference between the dark green and the dark red used to show the what is Login 0 & logic 1.

Could an option be made to set the colours used? Or, could the colours be made less dark? Or, could a patch or hack be made so that I can change the colours for him? If I knew where the colour in the .Exe or DLL were stored, I could edit the binary. (he uses win32)

    Thanks for your comment. When I get a chance, I will look at making this customizable. I am not a windows person, but in the libgpsimgui DLL there is the string "darkgreen" if you use a binary editor to change this to "green" ending with a zero byte ie (darkgreen^@ to green^@een^@) should give you shading difference with the red. I am just assuming this would work. If you have, of could get the build environment, the source change in gui/gui_breadboard.cc would be quite easy.

    Roy suggested patching the DLLs. However, under Win XP, the DLL he mentioned does not exist. However, after trying the suggested alteration on the .EXE, the colour difference is now a lot more detectable. My son with his colour blindness reports "usable", albeit not "easily usable".

    Thanks for the idea.

    On breadboard dark green changed to light green. This also helps with screen dumps to BW media
