I go with 3 to 4 stars too. Hard to start. Nontheless very enjoyable. Great logic. I love coloring. Thx.

Beautiful solve. Got stuck, but learned much from having to reconsider steps.

Since there are some comments regarding the difficulty and not finding the intended path, I will link a solution document in a hidden comment once I´m back from vacation (Feb 29th the earliest).

This was a beautiful puzzle. And, despite the sparse grid, I found it intuitive to solve. That said, it really stretched me. This was a very enjoyable solve.

Very nice puzzle. Definitely more difficult than the 2-star rating.
I'd say 3-4 stars in difficulty.

I have thoroughly enjoyed the Colorado series, and I think I must have missed something here because I found that puzzle at least 4 stars difficult. I think I might revisit it later to see if I can spot something simpler with fresh eyes. An incredible sparse grid this time!
Edit: Ahhh, the hidden comments. I saw my error immediately. A must faster solve coming right up.

Thanks everyone for solving and the kind comments :-)

Great Puzzle. I enjoyed the back and forth between determining the colours and determining the numbers those colours represent.

It's been a while since I enjoyed colouring my sudoku willingly. Beautiful puzzle

Very fun coloring puzzle!

Well, I couldn't find the logic, apparently. I did a bunch of coloring as a strategy, seemed to be going well, then hit a dead end. Took a guess with one cell that had two options and happened to get the right one.
