Right so this is Bastion Paint’s
photochromic pigment called Yellow. So when you’re indoors and there’s no UV
light it’s a white powder that will be almost transparent and when you go outside or
subjected it to a bit of UV light it turns yellow. I’m just going to speed it up by
putting it close and you can see the beautiful yellow color that develops in this powder.
So that’s Photochromic Pigment – Yellow. Thank you
