What are colours, in the context of particle physics?

Profile image!
This is a property of quarks (sub-atomic particles), which is analogous to electric charge. It has three states, which are denoted by red, green and blue. The colour of a quark is changed when it emits or absorbs a gluon. It is important to note that this has nothing to do with colour in a standard context, and hence it is a little confusing!
