gave me some trouble, but that's the nature of these large palindromes, I was chasing two 'different' colours, but were actually the same one...

Very nice puzzle, I normally find really long palindromes to be more of a chore than anything else but I enjoyed this one.
And it happens to be my 600 LMD solve, so thanks for the mini internet milestone.
A: Many thanks and congratulations on this achievement!
