R/G/B/A color scheme from -1 to 1 instead of 0 to 255?

So I noticed that some exporters and most of blockland's models seem to use a weird RGBA scale I've never heard about nor can find anything about on the internet. Apparantly instead of ranging from 0 to 255 on red, green, blue and alpha they range from -1 to 1. How can I convert the normal 0 to 255 one to the -1 to 1 version? Thanks in advance.

It's actually 0 to 1. Not -1 to 1.

Just divide your 0-255 numbers by 255 and they'll now be in the proper 0-1 form.

Ah, so it's just a percentage. Thank you.
