That's easy for me. Everything except mauves and lilacs etc. My house, when I bought it, was painted end to end chewing gum grey/mauve.
Not far off the colour of plaster in fact!!!
I can even cope with red as long as it's in amongst yellows and oranges.
When I went off to rummage in my stash for this project, it turns out about 50% of it is green!
