I hope this is colourful enough for the challenge! I found this scan and I couldn't resist! I added the texture, some brushwork overlays, and enhanced the colours. I tried playing around with the gradient, but I only changed that faintly. The text took the longest - most of that time was thinking what to write! A song by Plumb inspired me, and i've put this under cryptic, as I can't see where else it would fit!
