Line, color, and edge logic gets you through most of this. There's a bit in R15-21 C29-33 that's still unsolved, all green clues.#3: derby (Derby) on Jun 16, 2022 [HINT] [SPOILER]
R15: Regardless of where the green is placed, R17C31 is green. Do a little LL. Then when you're out of LL again, take another look at R15. Now you can see that placing a green in R15C31 causes a contradiction in R18, so R15C31 is white. LL can finish this off from there.
