Honestly, I don’t pay any attention to this at all. I just go for what I love.
My inspiration is Lorelai Gilmore 
Lounge is a pale mahogany wood with a floral pattern tile on the borders. Pale primrose yellow walls. Natural colour sofa and accessories.
My bedroom is pale cornflower blue walls with a ditzy floral frilly broderie anglais quilt and - white with cornflower blue and coral flowers. The main theme of the room is pale blue, coral and white.
Guest rooms dusky pink and beige and blush pink, white and grey. Grey and white bathroom that was already there when I moved in.
Kitchen is country style (no high gloss) cream units and duck egg blue metro tiles and cream walls.
My friends are all “show home” style - greys and whites and everything matchy matchy and that’s lovely but I want my house to feel like my home. I know my taste won’t be everyone’s taste but life’s too short to feel obliged to decorate according to whatever the trend is. Go with what you love.
I’ve lusted over Laura Ashley, Emma Bridgewater and Cath Kidston tat for too many years to go for the Narnia look as soon as I could afford my own home, even if means my house doesn’t match or fulfil the trends.
Go for what you love. If it happens to be on trend then that’s just a happy coincidence.
