Do you think green and blue go together and match?
…I’ll let my current nail varnish combination partially answer that one lol ;p
Green and blue just natually look amazing together though, because they’re analogous colours (i.e. they sit next to each other on the colour wheel).
Incidentally, my living room is even decorated in green and blue (it’s been that way for quite a few years now - the ultimate Lapidot foreshadowing XD)
