Found to be solvable with moderate lookahead by infrapinklizzard.#2: Joe (infrapinklizzard) on May 9, 2014 [HINT]
While this is quite hard, it's definitely not "lots of guessing needed".#3: Joe (infrapinklizzard) on May 9, 2014
Very careful color logic will get you to within 20 pixels of the end (five green in each corner).
Then extended edge logic on the top 2 in c6 will rule out r4 (or the 1 in c7 will be forced into r6 where the 2 will conflict with c6).
Then the upper left solves with line logic.
The same logic will work on each of the other three corners.
Prettier harder, you mean.
