Noodles- whole-grain, spinach, tofu or rice?

I know whole grain is healthy for your body, but so is spinach, tofu and rice. I just wondered what everyone's opinions are about the different types. Also, I've seen boxes of pasta with green, orange and yellow noodles mixed together, I'm assuming the green ones are spinach right? Are the orange ones carrot? Dunno what the yellow is :L
