Unfortunately that would mean a massive list of white from 149 down!
I don't particularly like Turbine's Colour Scheme either and some of them are far too dark to work in a forum post! {Dark Blue for instance would be unreadable!}.
I've gone with a 25 level split for Colours in the OP and tried to keep the colour changes successive i.e. White-Yellow-Orange-Red-Purple.
I could have gone White, Yellow, Green, Blue, Purple but that's by the by.
