What colour should I try to mix with yellow and why?

Baby blue.

Orange.

Purple. Purple Green and Gold are the Mardi Gras colours.

Red to make orange.

Or blue to make purple

@Dutchess_III yellow and blue make green. I think you should try red or green.

Green is not a primary color @KRD.

I stand corrected on my color combo tho.

Does it have to be a primary color @Dutchess_III?

If it’s only primary then all the answers are just a choice of two, red or blue, unless you want to also include white and black.

The 3 primary colors create every color you can imagine. If you add green you’re adding some combination of blue and yellow.

^^^^ Except sometimes you need a primary color and add white. Red and White make pink.

^^^^Yes. But neither black nor white is considered a primary color.

^^^^ So you cannot with “3 primary colors create every color you can imagine.”

White and black change the hue of a color.
