Experienced solvers might see the X in the red, but the logic for it is not usual.

Look at the 4 in c7. No matter where it is placed, there must be 2 red pixels right next to it in c8.

Look at the 4 in c9. The same thing happens mirrored - there must be 2 red pixels right next to it in c8.

Since there is only one 2 in c8, there is only one place that both those conditions can be met - in r4-5 where there are 3s. So the rectangle r4c7 to r5c9 (six pixels) must be red.

Then line logic to finish.

Found to be solvable with moderate lookahead by infrapinklizzard.

i saw the 'x' as a large chunk of smile logic

A woman of great wisdom!

Thanks Tom!
