You can use my cf for file name coloring on the command line, it's a quick little awk-based colorizer that works via pipes - coloring filenames in Truecolor sRGB.
It's got a brightly colored default configuration and unlike ls it does not suffer a performance penalty for adding new colors. (ls must scan the entire LS_COLORS string for each miss).
