Is this supposed to be the obfuscated Ada contest?
I mean, grey vs. bray makes my brain hurt.
^^^^ Of course, I meant to type "gray", but I like the
typo, so I'll leave it in. ;-)

Why do you say "probably gnat"?

This looks legal, to me. You're renaming calls to the enum lits (which
are like functions, in Ada). Perhaps you meant to say:
function Grey0 return Color_Type renames Gray0;
... and similarly for gr[ea]y1.
;-) But either way, it should be legal.
Package RGB_Value has nothing to do with this, as far as I can tell.
