Various
Variously
な adjective, adverb, noun, の adjective
The 々 character just repeats the kanji before it. In other words: color, color! But think figuratively, here — something with lots of different colors like this could also be described as various, which is exactly what this word means.
色々 used to mean a variety of colors, but over time evolved into a more general word for a diverse variety of something. You'll often see it as an adjective, like 色々な人 (various people), but it also pops up when talking about mixed experiences or actions, as in 色々あったね (a lot happened) or 色々考えた (I thought about it in all kinds of ways). Kind of appropriate how this word has various uses, eh?
The reading for this kanji is just the kun'yomi reading twice. Since you've learned the kun'yomi reading already, you should be able to read this word as well. Nothing tricky about it.
