zetamath Fog of War challenge part 4

[@emphyriohazzl1510]

Thanks for featuring my little advent-ure puzzle :P. It's a dumbed down version of a 9x9 I made a while ago, Framed Bats, which did require to notice the corner logic to solve it but also to notice that the remaining 2345 on the renban can be colored by couple of cells - in this 6x6 it would be r23c6=blue, r45c6=green, r6c45=blue, r6c23=green etc.. but of course neither are really needed in this intro puzzle ^^).

Thanks again Zetamath. Always grateful for your kind words.

In the first puzzle with a 56 pencil marked in r5c7, can we say that it's not a 6 because putting a 6 there would create a group of 10 mid line since it would be next to a 4?
