This is an entry for Fortnightly Topic Challenge #44: Introduce a new grid deduction genre to the community.
I've been dreaming up potential logic puzzles involving colours, and how they mix to form new colours. This logic puzzle uses the three primary colours (in the additive colour space, how light mixes) to form 8 combinations. I think I'll call it a Palette puzzle. (open to suggestions)
The rules are as follows:
- Fill each region with a colour from the list below
- The numbers along the side and top indicate the number of squares in that row or column which include that primary colour (red, green, or blue) in its composition
- No two regions of the same combined colour may share an edge
The possible colours are:
- Black (none of the primary colours)
- Red (only red)
- Blue (only blue)
- Green (only green)
- Cyan (green and blue, no red)
- Magenta (red and blue, no green)
- Yellow (red and green, no blue)
- White (all three primary colours)
The puzzle has a unique solution, but might require guessing (or looking far ahead)
Edit: Apologies, the solution is not unique, but you should be able to figure out the intended solution.
