What causes the star twinkling effect in the night sky, and why do some stars appear to twinkle in shades of red, blue, and green?

Oh, honey, those twinkling stars aren't playing games. It's good old atmospheric turbulence making their light dance, but ain't nobody got time for calm starlight, I guess! The colors? Yep, stars can show off their mini rainbow vibes, the twinkling sometimes breaks down their light, giving a little disco party up in your night sky.
