Highlight below for hints if you get stuck
Can you make any deductions about yellow cells in the perimeter?
Can you rule out any cells from being a 0?
Can an 8 be blue? And if so, under what circumstances?
What rule must a 1 follow in order to be blue?
If a non-perimeter 7 neighbours one 8, how can that 7 be blue?
0s, 8s, 1s and 7s hold the key to solving the first part of the puzzle.
Lösungscode: Top row (9 digits from left to right, with no spaces)

Incredible puzzle. I did so poorly and had to restart several times but loved it.

Wonderful puzzle and very challenging. I prefer this kind of simple rule sets that are easy to understand but novel and therefore hard to apply.

Great puzzle ! I was stuck for 80 mins because I couldn't see the white line against the yellow in the bottom row (for some reason the yellow was much lighter when solving on my phone). After that aha-moment it started to flow slowly but was still very hard.

Messed up on the first attempt about a month ago, but got it right today. What an awesome concept and execution! Thanks, @ marty_sears :).

Really enjoyed the puzzle! I definitely liked the unique constraint that every cell gives information about its neighbours. Adds to the challenge because it's not always obvious where the next break in the puzzle is going to come from.
