So i added the constraint that (Red - Green) must not be smaller than -64 and not larger than +32. This made the blueish impression quite stable. I also looked up in the web how to change the background color of an xterm from inside: # https://superuser.com/questions/592090/change-xterm-change-background-color-without-clearing-the-screen echo -n -e '\e]11;rgb:'"$rhex"/"$ghex"/"$bhex"'\a' (One should use a dedicated xterm for color display, because i don't know yet how to inquire the original bg color of the xterm.) > Is this a correct implementation? > (defalias '** #'expt) Lookth like Lithp. (Not my turf.) I think the ultimate test for correctness it the personal impression of the colors. Either by your keyborad lights or by above xterm color setting. Have a nice day :) Thomas
