I enjoyed the blue parts the best. Thanks.#2: Wombat (wombatilim) on Mar 9, 2023 [HINT]
Initial line & color logic gets to 74%. Green is complete; there is still black, red, and blue to go. It's possible I've overlooked some color logic but I don't think I have.#3: Web Paint-By-Number Robot (webpbn) on Mar 9, 2023
R30: EL places the remaining red 3 in C49-51. Resulting line & color logic finishes black and red.
C84: No matter how you place the blue 3, R25C83 is white and R28C83 is blue. LL.
R35: EL marks C9-11, C32, and C79-80 white. LL.
R34: EL marks C79-80 white. LL.
C80: Regardless of which way the bottom 2 goes, R33C79 is blue. LL.
R28: Whichever way the blue 2 between the greens on the right goes, R30C70 is blue. Minimal LL.
C77: Whichever way the blue 2 goes, R32C75 is white. LL.
R33: Whichever way the 5 goes, R35C74 is blue. LL.
R35: EL marks C67-C69 white.
Lots of LL gets to 96%.
R6: EL places part of the blue 6 in C25-26. LL finishes everything except a small bit in C44&C46.
R14: Whichever way the remaining 2 goes, R15C46 is blue.
LL to finish.
