88 - Desert Sunset (I think this actually be the colour in that blue burst pic robroe posted)
95 - Starlite Blue
97 - ? (it mentions redstone in one old colour chart, but the same chart also has silver sparkle as an 8x number rather than 17. As far as I'm aware they never used 97 again so it would still be redstone and finding any image at all is probably a lost cause)
I've been looking around and did actually come across a couple that were missing. I think it would be possible to get perhaps towards half of that list with a fair bit of searching. I have two copies of frontline (2001 and 2002) that actually have stock pics of a few of those colours but I've no easy way to scan them. If you have some 90s or early 2000s frontlines and are able to scan images at decent quality it would be much appreciated if you could get a few of those.
And just so you know it's all worth while, this is what you'd be helping towards...
