I need to convert all of my file's colors to RGB.

Most of them are already RGB. There are 2 CMYK and 1 Registration.

I can edit the RGB colors into CMYK with the Edit button, but not the other way around. enter image description here

Any idea how I can do this in Scribus? Or do I need another program to do it?

    Did you actually use the 'color' Registration for anything? It has a very specific use in CMYK printing, but for RGB use you should simply use black.

Registration Black, (CMYK Black), and CMYK White are protected colors in Scribus.

Personally, I think that this limitation should be removed, but I'm not sure that it will ever happen.

For now, you can just ignore those colors: if you don't use them they will not affect your exported document.
