I forgot to say in my first message that I see the "dots" in the colors at
256 colors. Based on the email I've received that would have been a good
idea to mention. (Duh me!) That's what I'm trying to get rid of. And
shouldn't browser safe colors stay browser safe, especially since there are
only 5 colors in the whole thing?

The RGB values definitely changed value when converted to gif. And the
small versions were made by first reducing the original PS format file,
then converting it to GIF.

I only get the Digest version of this list so I don't yet know what else I
may have forgotten to mention.

converted to GIF just fine. Then I reduced the original (PhotoShop 4) and
converted to GIF again only this time the colors are no longer browser safe
(I get those irritating little dots in the colors).

it on the small ones, but not the large ones, unless that matters.)

something I can do in the convert process, but what?
