I was just looking at these today - there are three variants with different degrees of white, so might need to check which you are ordering. If they are going to be outside you probably need the IP65 or IP67 rated variants. If you look around on aliexpress you can find both black and white colored strips.
I got started down the rabbit hole when I saw ads for permanent light fixtures for housing. The idea is you install the lights once and then you can use the color changing ability to create appropriate displays for different holidays throughout the year.
