Do as you wish with colors. Trends change, statistics change. Styles are always moving bc it's how people make money.
I am old and both dm and dgm collected antiques. I probably know more about decorating than 6 people need to know.
THIS is what I've learned after decades of estate sales: it doesn't matter.
I've been in perfect homes by fancy designers, pretty homes by talented amateurs and hoarder hovels.
Not one of those or any other category had a lock on happiness, peace or any other important thing in life. Including offspring success.
In fact, some of most "perfect" homes had most miserable adult children.
One friend had spotless home. Her dd attempted suicide. Another person who struggled with chronic illness and housework: dd at top uni.
What children need is love and attention and happy, patient parents who also have common sense.
Also. Keeping up with anyone is useless. I knew a group at school who HAD to follow Mrs.HappyPants. Grrrrr. I watched them bow and scrap and follow her lead. Mrs HP moved. What was the outcome?
Nothing. Years spent ignoring their own ideas for someone who left. What.a.waste.of.time.
Yes, i think that some trends need to be followed to help children fit in.
However, your home? Don't waste your life following trends. It's not as important as following your own likes and dislikes.
My motherinlaw put her home above all else. She's dead. Her much loved stuff is being split up or sold. This is her legacy; nice things her family resents bc she liked it more than her dgc.
When i die, i want people to say i was kind funny, loving, staunch defender of my loved ones and i didn't follow trends, i did what i wanted.
Do what you want. Life is sooo very short and fragile. Gray. Rainbows. Pink or blue. Enjoy it bc dc will be grown and annoyed at you very quickly.
