What version do you need to view astro colors, and anyone have a link for it? (I use standalone)

You need 5.22, and as far as i know that version currently just for steam version. If you want to see it either you download the steam version or ask someone who has it for a screenshot (If you just want to look how it looks that is)

Oof. I actually wanted to wear it. Is it planned for it to come out on standalone anytime soon?

I don't know when, but probably there will.

If I remember correftly...

Sir told me he'll release the 5.22 standalone version next month with another new update
