The problem I have with colours is that I can't see any in the answers I already have, where "2" is mentioned, TINPOT for 5a ( Insignificant river in 2 )
OK...PO is a river and TINPOT could mean insignificant but where is the colour in that ?
Ditto with 6a...Strong river in 2....ROBUST. Again, can't see any colours.
Are we sure its colours ?
He's a crafty bugger is our Araucaria, so its probably there somewhere !
