Mauve back in the 80’s if you want to include that. I never owned any that color, but I definitely saw and used towels in that color.
I like white, because you can use harsher detergents and bleach if you need to and also if you use peroxide toothpaste you won’t have to worry about the towel color bleaching out in spots. I like towels that are on the thinner side and not too soft and I like a decent size that wraps around well. Too soft and they don’t absorb water well. Too thick and they don’t dry fast enough.
I like my luxury coming from my bathrobe once I’m reasonably dry from using a towel. Put on my robe, and finish drying just sitting around or while I dry my hair or make breakfast. I have robes for guests too, but half of them don’t use the robes.
A guest pointed out to me that they prefer different colored towels if they share a bathroom with other guests so they easily know which towel is theirs.
At the apartment where I am now they have Standard Textile Luxury Stripe towels, and they’re fine. They don’t feel luxurious, but the towel holds it shape well (some towels get deformed after one time through the dryer) and I like them for a standard towel. I probably wouldn’t buy the striped pattern myself, but otherwise it’s a good towel. I’m not at my house to look at the brand names of my towels there.
