What a great image! I really enjoyed solving this one.

That was quite hard. Nice image.

I had to make a couple guesses, but then it flowed nicely.

Very good puzzle and excellent image. For me the trick to solving was to figure out where the second group of five pixels could go in the third row from the bottom, but even that was a few reverts. I love that it wasn’t predictable. Excellent. Well done!

great image and a very rewarding solve.

Thank you all for the kind words! I'm glad that you liked the puzzle!

This is the first "serious" puzzle I ever post. I've used a solver of my own making to design it!

Absolutely beautiful!

For me the key was the ten in c33. Once I realized that it could not go as high as r15, the rest was easy. Figuring that out was not.

Found to be solvable with deep lookahead by wombatilim.

Initial line & color logic gets to 49%.

C36: If the top 3 goes into R18, it puts blacks in R18 C32-36. If it goes into R21, it puts whites in C28-33, and R18C30 must be black, which also puts blacks in R18 C31-32. Either way, R18C32 is black. Minimal LL.

C33: EL marks R34-43 white. LL.

R43: EL v. R41 marks C20-32 white.
R42: EL marks C6 and C21-32 white.

C32: EL marks R37-41 white.
C31: EL marks R37-41 white.

Deep lookahead C35: If the first 4 goes into R17, R18 C28-31 would be white and R18C36 would be black. R21C30 would need to be black, placing part of the 3 in R21. The 10 in C33 would be in R11-20 and the 6 in C34 would be in R15-20. This would place blacks in R14-17 C31, making C31 invalid. R21C35 must be black instead.

LL to finish.
