Very random, but what are your favourite colour pairings?

I really love the combination of neon green and black. That shade of green is such an 'in your face' colour and the brightness contrasts with black strongly. But two pairing I will always show I love is blue/black and blue/white, any shade. I really love blue, if I stop lying about neon green being my favourite colour, blue would be my favourite. I think it's because of me writing stories that made me love blue so much, and subsequently black and blue. And the same for white/blue. Definitely not possible to find out what character did that. Actually, my favourite hair/eye colour combo is white/blue. Doesn't that sound familiar..?

Maybe it's because of a strong bias that I love Morfonica's costumes. White, blue and black. But what other colour could have worked? I think none.
