Review on Faber Castell Gel Crayons Vibrant by Duane Mejia

I usually like everything Faber Castell makes. I'm an art teacher so I chose these gel pens over others because of the good reputation of the brand. While the quality of these gel pens is good, this set has one major problem! PURPLE NO! You need purple boys! I tried mixing blue and red but it didn't turn out a nice purple at all. I don't want the silver or neon yellow that comes with the kit. I need purple! I would like to see a larger set with all primary, secondary and intermediate colors. I prefer pastel to neon.
