There will always be those @Susan1639 who will argue one side or the other.
I’ve tried both doing homestays and Airbnb, and my choice is white. I can kill them with whatever products I want without fear of altering the colour. You can always match! Even if there are a thousand shades of white.... if you maintain a reasonable standard of thread count, they’ll be fine.
Coloured sheets will fade, and non removable grease marks etc just get darker.....
White sheets will yellow or be killed by artificial tan, scalp oil, etc over time. They need tossing if this happens, so plan your pricing around at least two to three sets and purchase during specials and put aside. I say three so if you have a quick turnaround and some stubborn stains that need major soaking: One on, one off... and one in the wash!
