ELI5: So I found out that space telescopes capture "colors" that weren't there to begin with and see in black and white. What colors are really present in our universe?

EDIT:

To clarify, the Hubble colorizes white and black images by adding colors to represent the spectrum. I'm just wondering "what colors are really present in our universe," as in, what colors are actually out there in space? Not how they color it. That's my bad.

You might be mistaking a few things, lots of telescopes CAN capture colour, others do not. When you see a false colour image it isn't that the microscope is detecting something that we dont see, false colours are just substituted for other values to make things easier to see. For example, we cant see infrared radiation, but we can detect it with IR cameras, however in order to make sense of the data we colour different values of IR detection with different colours to create a "predator vision" type of image that can be useful to us. Similarly there are lots of telescopes that dont operate in the visual spectrum, they detect xray, or IR, or gamma bursts or microwaves, or some other portion of the electromagnetic spectrum, and we give these wavelengths false colours so that we can more easily visualize them.
