I love all the different colours, cute puzzle, Thanks potatomum.

Super puzzle!

Nanax4 - I thought so too!

PG - hilarious - I was thinking that too. :))

Lyndee - Dunno. I guess because if it was all one color it would be easy to get confused. Must be color-coded for some reason other than for fun!

I wonder what is the reasoning behind the different colors. Nice puzzle.

And the music goes round and round and it comes out here.

Neat!
