The Pink/Red color is a combination of BB's Tangerine Wow & Aztec Florescent Magenta Colorant, the Orange is Aztec's Fluorescent Orange Yellow Colorant, & the yellow is Bescented's Canary Yellow. and of course TD, I use the oil soluble kind, & plain no color part as well. I love adding in some of the soap without any color added to show any slight bit of discoloration. I try not to get FO's that discolor too dark as well though.I love the your design, esp. with the vibrant colors! Are those Nurture neons?
