I have a couple of grey rooms so it's nothing to do with disliking the colour grey. I happen to really dislike magnolia though.
There's many ways to style any colour. I'm not buying the idea that a sudden surge in grey and white everything, grey and fluffy carpets, grey velvet sofas, mirrored stuff etc is because all these people suddenly realised that was just so their style.
Why would home decoration be any different from fashion:
Some people have their own style and are comfortable in certain styles and colours, regardless of them being in or our of fashion
Others have their own staple style and add in bits from each season throughout the year
Others don't think for themselves and will wear whatever is 'in' because they like the feeling of being 'in' (regardless of how it actually looks on them)?
Certain interior design trends are no different from people wearing fast fashion trends. Eg Those signs that say 'bathe' in the bathroom, the Hinch grey look, pastel crushed velvet sofas, the bold wallpapered feature wall a la Changing Rooms.
Of course the aim of Mrs Hinch is to get her followers to follow the trend. That's how she makes money by telling people where to buy stuff she's been given or has been paid to promote. She's no different from other influencers in that's respect, but influencers only work if there is a herd to be influenced.
