Quarks are never observed or found in isolation due to a color confinement phenomenon; they can only be found within hadrons like baryons (of which protons and neutrons are examples) and mesons. Other particles electrons, neutrinos, photons and more can exist on their own. The color assignment of individual quarks is arbitrary, but all three colors must be present; red, blue and green are used as an analogy to the primary colors that together produce a white color Protons and neutrons can be further broken down: they're both made up of things called quarks. As far as we can tell, quarks can't be broken down into smaller components, making them the smallest things we know of. Gluons bind quarks together, forming hadrons such as protons and neutrons. Despite their minuscule size, a number of much smaller particles exist, known as subatomic particles. A preon (of whatever mass)s momentum uncertainty is about 200 GeV/c in a box of this size, which is 50,000 times the rest mass of an up-quaark and 400,000 times the rest mass of an electron.

The simple summary of Mead's answer is that it is impossible, using the known laws of quantum mechanics and the known behavior of gravity, to determine a position to a precision smaller than the Planck length. Thus, protons and neutrons are no more indivisible than atoms are; indeed, they contain still smaller particles, which are called quarks.
