Also on board with grey gatsby

It's got a decent hold (not sticky .. best way to describe it is like when you iron a shirt and the shirt holds the lines). Gives you a really good matte finish too. I actually bought all the gatsbys and treid them out. My observations:
1. Green - works great for details. I was into doing japanese style crazy hair for a while and i used this for the crown of my head and some details work. Nice consistency, not too sticky, and more of a matte finish
2. Grey - My fave. Ultra matte finish and not stickey (think grungy hair). This stuff works better when I have short hair or want to do some details in the hair (see green). It actually gets even better after about 6-8 hours of wearing it, as you can mold it and play with it more and it still holds whatever you throw at it.
3. Purple and Orange - These feel way to 'greezy'. I tried with short and long hair and didn't like the results.
5. Blue - Works great for medium/long, as it gives your hair the wet look with very very light hold. Does nothing for short hair.
I think I'm missing one.
