Works Great!
A little goes a long way so be careful with using too much product. I use it to color macaron batter and it does a great job at that. I haven't tried it in cake batter or in buttercream. The amount you use also dictates the vibrancy of the color so if you want a light green you can achieve it by using less powder and if wanting a more darker green use more.
