OK, firebrick2 is a good color for `Hi Red B'.

'light green' is almost white, so it's difficult to read on
white background when 'light green' is used as foreground color
in `Hi Green B'. This is the reason why 'light green' is used as
background color in `Hi Green', i.e. 'light green' is better
for background, not foreground.

The same way as hi-yellow is defined to use yellow, and hi-green
to use green, we can define hi-blue to use blue color, and
hi-pink to use red color.  This will free cyan and magenta
to use.
