After using Oleander and being disappointed by the lack of colour vibrancy in a bathbomb (which I expected), NurtureSoap was kind enough to lend me a discount coupon and I tried Amaranth after some deliberation. The colour is simply stunning! It is soft, sweet, blush, and gentle: the pink is the perfect pink, and it will be my go to for all future pink products that my sister and I create together: I attached a lovely little video of me swirling it with some dried rose bits. Unfortunately they lost some of their colour, but, the water is the pure quintessence of pretty.
I will be buying the absolute heck out of this colour, from now on!
