Before you sell, you can paint everything beige, or put in a “paint allowance” if your colors are REALLY bold (i have a deep turquoise in my home office) ... But I love color and we have a lot of it in our house... there’s a deep joy in having your home be the colors you want.
The house next to me is going up for sale and the realtor is in charge of fixing it up for the owner, who lives elsewhere, and I really really hope it's anything but beige or light gray. Fingers crossed it's at least that white with black trim that is trendy right now. I too love color and yellows and blues are big in my house (our office is teal-ish, kind of like your turquoise).
