Hi
We did a biggish refurb lately & now need to redecorate practically all of our house.
My head is wrecked trying to choose paint colours. I'm close to repainting the previous colours just so I'm done with it! My favourite ever was this colour in my sitting room but it seems very out of fashion now.
I'm trying to like this new grey thing, but I don't. I live in Ireland, where the sky is varying shades of grey 75% of the year, so I don't think I need it on my walls. I gravitate to sage greens/duck egg blues but I'm concerned they're a little dated now. That was all very 2000's wasn't it?
It's so unclear which undertones go together! Im bankrupting myself buying tester pots 
Are there any tricks to choosing paint colours & how to get the right undertone?
