Now I see it is using `char Output::color_COUT[MAX_ESC_LEN] = CSI "0;30;49m" ;` in code, it is strange that reset background while set foreground to black. I think it quite normal to use default (reset color) color for std::cout, i.e. use `CSI "0;39;49m"`. I know it could be set in /etc/gnu-apl.d/preference, while we are talking about the default behavior. Thanks, Clouds
