Are Kirkland bed sheets bleach resistant?

Kirkland bed sheets are currently on a $15 off coupon. I use a topical medicine that bleaches sheets & clothes so I’m wondering if anyone knows if they are bleach resistant. If not, they will get bleached to hell quickly.

The online description doesn’t mention it either way but that’s not the full care instructions. I may just try the white sheets but it’s nice to have color options.
