Find the CG crayon!

I created a crayon shader for shader programming, it still needs a few tweaks, but I am pretty happy with how it turned out.  Can you guess which crayon is fake?

When class assigns you a lemon, make lemonade

Here is my finished Lemon shader! I might tweak it later, but school is pretty busy. I don't know how in the world it turned out this good.  I attribute it to Heavenly Father and lots of prayer. :)
