Yes they can! It depends what they are made of. Our moon is made of rocks like earth so it is grey and white because there is no weathering or anything to change the colour.
The moons of Jupiter are very different colours because they are made of things. Europa is white ice with a bit of red, though we don’t know what the red stuff is. Io is yellow coloured because it has lots of sulphur volcanoes. And Callisto is black and orange because it had been burnt and smashed into by so.many meteors.
Space is so big, if you can imagine it, you can probably get it!

Definitely. Most moons are fairly boring – they’re probably old asteroids so they all tend to be pretty moon grey and covered in craters. But like leila says, the moons of jupiter are pretty cool.
here’s a pic of 4 of them

I guess that would depend on what they’re made from. Io – a moon of Jupiter has sulpher volcanos and looks a bit like a pizza.

The colour we see is partly because of what the surface is made of (and how fine the particles are: when they get really tiny, they tend to look grey/white). Io is yellowish-brown-whitish because of the sulphur that errupts from its volcanoes. I think the Titan looks a smudgy brown colour, because of the clouds of methane in the atmosphere. And some moons have black bits because they were hit by asteroids and that went through the surface to show the darker stuff underneath.
If you look at the moons in light invisible to the eye, like UV or infra-red, you can colour them in depending on what minerals and chemicals are on the surface. Then it can look very different!
