thx gang :)#9: Wombat (wombatilim) on Jul 21, 2017 [HINT]
initial line & color logic solves all of the red & blue, and starts the black.#10: Web Paint-By-Number Robot (webpbn) on Jan 23, 2024
EL C29 requires R14-17 to be white. LL.
C27: If the 2 clue goes into R19, it causes a contradiction in R18 or R20. LL.
EL R1 requires C1-9 to be white.
LL to finish.
Found to be solvable with moderate lookahead by blurglecruncheon.#11: Andrew Schultz (blurglecruncheon) on Jan 23, 2024 [HINT]
C1 edge logic (maybe not necessary,) C29, and R1 and R2 edge logic. Also two way logic to make dots at R18C25/24.
