what colors go together clothes
With a colour like purple, pairings should be in pastel shades. Jeans go great with a light purple shirt. White, cream, ocher, khaki, pale brown etc also go well. You don't want two bright colours together, they look horribly clownish.
I think when you are matching colors, it's not so much which color you match but which shade of it. Anything with blue in it (even yellow with blue in it, if that makes sense) goes best with other colors with blue in them, etc. Deep plum purple that has much warm red in it goes well with other similar colors.
