Greens you can get from fresh herbs, but they tend to be more olivy than bright green, or you get a speckled effect. Spinach works, too. Tomatoes give you an orangy-red. Probably get some interesting coloring from those purple potatoes; I haven't tried that yet, but purple gnocchi would be interesting.
Blue would be the hardest to get without resorting to food coloring. But blue coloring is pretty strong, so you probably wouldn't need too much.
Eh, I'd rather just wear these.
Most of those you could even get from peppers, if your local megamart happens to stock lots of diverse bell pepper varieties.
as for the big bold yellows, turmeric would also be totally viable, though not all that amazingly tasty alone. And taro, again if you can find it, has a nice lavender-y shade, which wouldn't help for a strong purple, but a definite one anyway.
