As far I know it is pretty much impossible to figure the foreground/background colors of the terminal you are running on. You can try some guesswork based on $TERM (linux console usually has black background, xterm is white by default), but there will always be cases where it fails. You can run without colors. You can use bold to highlight things and reverse for the cursor. Surely a bit limited and not as pretty as colored, but works for sure everywhere. You can go for a linux-console style black background. Pretty much any color is readable here, so you should have no problems at all to find the 5-6 colors you want. You can go for a xterm-like light background, for example the lightgray used by older perf versions. I like that background color, problem is with most colors the contrast is pretty low. IMHO only red, blue and violet are readable on lightgray. And black of course. > Plus allowing full .perfconfig configurability of all the relevant > colors, for those with special taste. Sure. Maybe also allow multiple color sections and pick them by $TERM or --colors switch, i.e. [colors "xterm"]. cheers, Gerd -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
