The New Sudoku Players' Forum

I'm new to the forum and have a question about solving with colors. After coloring one candidate in a unit (line or box) how do you color other canidates when there are more than one in the same unit? All with opposite colors, or alternating them (same, opposite, same, opposite color, etc)?

Thanks for any guidance!

Hi Renald,
I posted a pdf on solving techniques here:

It shows how to do simple colours and colours on multiple candidates. It might help you.
