Hello, I've not got any gummi bears at hand but from what I can remember they are a sort of sweet made from jelly. This is how I would make that sort of colour, I would spend a lot more time refinng the shader if it was for me but this should give you an idea. Under the raytracing tab I set the refraction to 1.3. Like I say I did this very quick as a guide and there are many other ways to make a shader but it should set you on your way. Good luck, Mat.
