This one was tricky to solve, might need guessing, but I leave it to the experts.
In any event, make sure they are logically solvable, that's one of the challenges.

I really enjoyed the solve.....in the end I did the lower red by trial and error but it made the puzzle fun to solve. Thanks!!

Initial line & color logic completes 76% with only red remaining.

C1: If R14 or R15 is red, it creates a contradiction in C2, so these squares are white. LL.

C3: The reds in R12-13 are either the 2 or part of the 5. If they are part of the 5, it causes a contradiction in C4 (The red in R9C4 would need to be the bottom of the 4, but it would connect to R5, for a total of 5 squares instead of 4). Therefore, R12-13 C3 are the 2 and R11C3 is white. LL.

C6: EL marks R18 white.
C2: EL marks R25 white.

Currently at 93%, and I'm not seeing a way forward right now. I know the red in R22C4 is part of the 2 in C4, and I know the 3 in C6 can't cross both R21 & R22 but I can't eliminate them individually.

C2: If the 3 goes into R22, regardless of its placement from there, it places the 2 in C3 into R21-22 and forces the 3 in C6 to go into R23-25. This makes R19 invalid, so R22C2 must be white.

LL to finish.

Found to be solvable with moderate lookahead by wombatilim.
