Kropki pairs: digits separated by a white dot form a consecutive pair. Digits separated by a black dot are in a 1:2 ratio. Not all possible dots are shown.
Modular lines: every set of three sequential digits along a line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}. Digits may repeat on a line if allowed by other rules.
Play this puzzle on CTC.
Solution code: Row 1 (from left to right)

Tough but fun. Very creative use of grid geometry. Thanks, @ FullDeck-Missing :).

It was a very nice and hard puzzle to solve. I liked very much the logic behind it. Thank you!
>> Thank you! If you like the constraint, there will be two puzzle packs using modular lines coming out through Cracking the Cryptic sometime in the near future (possibly even today). One will be unlocked with six puzzles and the other, with 18 puzzles, will be locked for just Patreon members. Six of us put it together: the two of us and JC Godart, jeremydover, Raumplaner, and rockratzero.

So hard! And very very nice.

Great idea and construction.

great idea to use those modular lines, makes for a nice coloring puzzle.
however, the final disambiguation seemed a bit forced.
>> Thanks for the feedback, slowbiex. We appreciate you taking the time to share it. Lots of interesting logic comes up with the modular lines constraint but without either giving digits or adding arithmetic clues such as killer cages or little killers, disambiguation is driven only by the resolution of the kropki dots which means it all happens at once. We saw that as a fun way of having the puzzle all open up as a huge reward to the solver once the coloring was done; sorry it felt forced!
No, I'm sorry if my comment sounded disrespectful - it's still a great puzzle and I'm grateful!

Looking forward to the whole pack, it's a good thing I'm a CtC Patreon :-)
