This is just playing with combining some techniques, namely the taping and stippling for gradients.  I started with a base of Color Club Catwalk Queen, a super dark purple shimmer number (what is with all the purple lately?! I gotta cut myself off), then taped off a triangle at each tip when it dried.  I first painted it in with Sinful Colors Fusion Neon, used a black striper to add a couple of lines, then went in and sponged some Color Club Warhol over that.  It’s a kapow sort of look for sure.
