I'm guessing that's a rock and a roll. So we built this city on stone and bun!#2: Web Paint-By-Number Robot (webpbn) on Sep 29, 2022 classify

Black and blue are solvable with just color and line logic.
Red needs advanced logic to start
Edge Logic 6 r40 = c3-6, c17-19 white
LL
EL 6 r26 = c3-7, c15-19 w
LL
EL5 c19 = r30, r37-39 w
LL
Distant EL 6 r40 (vs r37): If the 6 were to go right past c14, it would invalidate r37 (because of the 4|3|3 in c14-16) so r40c15-16 must be white
LL
EL 5 c3 = r39 w
LL to finish
