Let's Color!
If you have a printer and media (crayons, colored pencils, etc), get to coloring. The last one doesn't require anything that you don't have.Color Our Collections

Book Riot has curated a great list of artists who offer free coloring pages. I’ll just look bad if I go searching on my own, so go to BookRiot.
No printer? No supplies?
Coloring.com is a pretty decent online coloring site.
