Carotene is called carotene not because it exists only in carrots, but also in broccoli, spinach, mango and other plants. So named because it is orange-red like carrots, so it is orange-red. Including Nutrilite beta-carotene capsules, which also contain liquid of this color. If the landlord refers to the obvious orange-red appearance of the capsule, it should be too long before the capsule is destroyed and the liquid inside penetrates into the epidermis.

I hope my answer will be helpful to the landlord.
