terminals do have the concept of "blue" [...] Terminals are generic. Any kind of program can run in them. I gave the ls example (which bothers just because I'm used to blue for folders), but other programs may run where "blue" isn't a code for representing some other concept - it really means "a blue color".
NOTE: depending on the blue you choose, you might want to tweak ANSI cyan as well so that the purple/blue/cyan contrast is consistent (not too much or too little) with the contrast in the default colors you usually find in terminals (e.g. Ubuntu bash).
The current

is actually purple from the palette, which is too different to be considered "blue". Please consider adding a blue-ish color to the standard palette, or at least use a proper blue for blue and bright blue ANSI colors.
