You can use coloring just to remember particular interesting squares. As either orange or turquoise must be correct and not both must be correct that proves it! If the orange squares are correct then Bf can not take a 5 but nor can it if the turquoise squares are correct. Having marked the alternate pairs it is evident that square Bf (lime green) can not take a 5 as it is in the same column as a turquoise square and the same row as an orange square. In addition there is another pair Bd (blue) and Fd (red) in column d. This square is in turn paired with turquoise square If. Next Hg is paired to orange square Ii as a pair in region Gg. Only one of these two squares can be the '5' in column g. Starting with orange square Bg this is paired to turquoise square Hg. Alternate pairs have been marked with different square colors. In this example puzzle screenshot, coloring has been used to identify squares that can take a 5. The colors are added from the right mouse menu or the Edit menu or, using the keyboard SHIFT+Function key. There is a command to quickly clear coloring from all squares in one go.
