> While reading tty-colors.el with colorful-mode turned on, several colors were not being highlighted, I tried with rainbow-mode to see if it was an "issue" with colorful-mode but it gave me the same result.

Are you saying that the problems with colorful-mode are due to
differences in spelling of the color names in tty-colors.el?  If so,
please show the details.

This should not matter because we canonicalize the color names before
accessing the color-name-rgb-alist:

  (tty-color-canonicalize "Ghost White")
    => "ghostwhite"

Thanks.  Unless you have a situation where this causes some problems,
this is not a bug.
