Thread Subject: Color format?

What is the color format used by most GUI properties that ranges from 0-1? How do we convert it to RGB (0-255)?

Thanks.

normalized rgb...

% hence
     guicolor=gray(3)
     rgbcolor=255*guicolor
%{
% guicolor =
            0 0 0
          0.5 0.5 0.5
            1 1 1
% rgbcolor =
            0 0 0
        127.5 127.5 127.5
          255 255 255
%}

Just a very minor point. 'Us' has titled his explaination as normalized RGB. This phrase is often used to describe a totally different colour space, which is an effective intensity independent RGB colour space, which bears no relevance to the original OP's question. I added this so as to prevent the OP from getting confused if he Googles Normalized RGB.
