prompt colors bug? also possible feature add

Hi all,

While working on colors and prompts I noticed that gray and grey
do not work in a prompt. But in the colors function it states:

# This is inaccurate, but the prompt theme system needs it.

for k in grey gray; do

Also wondering, since bright colors were added to colors, were they also
going to be included in prompts? That said, my $0.02 - I'm happy that all
16 colors are there in numbers 0 thru 15 and works as expected.

Is there any reason gray and grey couldn't be set correctly by using \e[38;5;8m
and \e[48;5;8m?  Just a thought. Even the linux console supports all 16 colors.
it just doesn't support bold.

Attached is a function I wrote "test_prompt_output.txt", and two png files
