XVXVX (Stitched Rainbow III)
(Published on 21. October 2021, 18:47 by thoughtbyte)
Normal Sudoku rules apply. Additionally:
1. XV XV: cells separated by a V sum to 5; cells separated by an X sum to 10; cells separated by an XV sum to 15. No negative constraint.
2. X: digits along the main, marked diagonals cannot repeat.
3. Little killer: clues outside the grid indicate the sum of the cells along the marked diagonal.
If you enjoy this puzzle check out my other XV coloring puzzles: Stitched Rainbow, Stitched Rainbow II, and Disjointed Rainbow.

My tip for these puzzles: work with both letters and colors. Use light green and soft pink for low digit pairs, dark green and red for high digit pairs, with light and dark green pairing up for the X and so on. Use letters to distinguish between two light green digits. I find this keeps the puzzle from devolving into kaleidoscopic madness.

Another lovely puzzle Thoughtbyte. I really enjoy the flow of your setting.
@ddurschlag, I’m colourblind, so the CTC app functionally only has seven colours for me (silver, grey, black, yellowgreen, bluepurple, orange, and red). But I used the drawing X/O function to differentiate individual digits in pairs.

Made me wish the CTC app had more/worked better with colors!
