Do atoms and subatomic particles have a color that we can observe? 

My common knowledge on this topic suggest that atoms should have a color and that is why we see different elements (gold, silver, etc.) in different colors. But i'm still not sure if that is correct. And that made me also think about protons, neutrons and elecontrons. They do reflect light, so they should "produce" a color that we can observe. Is it the color of their atom? And what happens if there is a covalent bond or another type of electron exchange between atoms?
I'm sorry if my question isn't clear. This is my first post in this subreddit.

The phenomenon of colour comes from the way a material reflects (or emits) light. This is almost entirely a result of its electronic properties, which depend on both the atoms present and how they interact with one another.

We see different elements to be different colours because of their particular electronic structures. These are generally actually different to the structures of individual atoms. The presence of covalent bonding, as you suggest, may be one thing that changes the result.

Subatomic particles don't really have colours individually, because colour is a bulk property resulting from their interactions with light in the context of whatever they're surrounded by.
