I have made up the sentences below.
(1) I like to wear any colour clothing. I'm not choosy.
(2) I like to wear clothing of any colour. I'm not choosy.
(3) I like to wear clothing in any colour. I'm not choosy.
Which one is correct? Thank you very much for your help
Why not just say It's not important to me what color I wear. I'm not choosy. You can even say I don't care what color I wear.

Why not just say
It's not important to me what color I wear. I'm not choosy.
You can even say
I don't care what color I wear. I'd just as soon wear any color.
As for your choices, they're all acceptable. I'd use "of" rather than "in", but "in" is not a terrible choice.
