Back by popular demand, another C64 challenge. There's a lot of info here, so make sure you actually look over it.
There's no specific theme this week, instead you must only use 4 colours out of the available 16. Your piece does not have to adhere to any particular C64 restrictions (these are detailed in the links below). However, it must use one of the palettes shown below - either Pepto's palette, or Ptoing's adjusted version of that palette.
Optional Bonus Challenge: Use correct mcol (multicolour mode) restrictions - this means create the image using double width pixels. See the first link below for more information on different modes.
A bunch of useful links and a Grafx2 script:
Canvas Size - Exactly 320 (width) x 200 (height).
Colours - Exactly 4. Pick 4 colours from one of the 16 colour palettes below. No palette swapping, you either use Pepto's palette or Ptoing's palette.
Transparency - No.
Animation - Optional.
The challenge thread will have all the challenge updates. The thread is also a great place to post your WIPs.
