Re: problem in converting gif to rgb

RGB is a raw RGB file, i.e. the RGB values being stored for each pixel. 
If you type

convert -size 2x2 -xc:seagreen1 test.rgb

the file should be 24 byte (with IM Q16) and consist of four times the 
hexvalues

54 (54) FF (FF) 9F (9F)

These are the RGB values of seagreen1, see 
http://www.imagemagick.org/script/color.php.

If this is what happens on your computer, too, then the problem is 
probably on the side of the image viewer that you use. (Which is?)
