I like the method for checking decrement and increment numbers though it's not universal. I believe putting the conditions which is more likely to be true can improve the time efficiency.

i think, this line - "for num, color in zip(range(number, number+3), (2, 1, 1)):"
should be like this - "for num, color in zip(range(number, number+3), (2, 1, 0)):"

Very well organized ideas. Readable, simple, maintainable. Splendid use of Python's features. The formatting is neat but not best practice.

nice use of iterations, that's sweet

Clever solution. I just made mine unncecssarily complicated, at least part of it.
Learnt new stuff.

so elegant, well done.

Well, fml.

That's great, nothing will explain it better, you need a promotion

arousing

lol, Agreed. I fully understand what its saying though, which is nice. its not so esoteric that I feel like I need to dust off an ancient manuscript.

It means if 0 comes after 9, 0 can be seemed as 10, but 1 shouldn't come after 10

Very nice

For incrementing sequences, 0 should come after 9, and not before 1, as in 7890

No.
