Not an expert on this at all. But, I believe that all the websafe
colors are defined in pairs of the following hex digits. 00, 33,
66, 99, cc, & ff.  So only colors that are composed of those
pairs are websafe.
If that's true then yes there are shades of gray that are not web
safe. Checkout this link for more info.

Therefore there are only six shades of websafe gray. 000000,
333333, 666666, 999999, cccccc, & ffffff.

Put those in a list?
