Color match game

This is the equivalent of an old Amiga game. Your task is to find the correct mix of primary colors in order to obtain the requested color. Push on TEST button to see if you are correct.
 Here the source:

REBOL [
    Title:   "Colormatch 1.5"
    File:   %colormatch15.r
    Author: "Scot M. Sutherland"
    Verson: 1.5.1
    Date: 15-Mar-2007
    Copyright: "©2006, by Scot M. Sutherland.   All rights reserved."
    Purpose: {Color Match 1.5 simulates very closely the Amiga Version created in 1987.
Junior High students learned how to created accurate colors by typing in numbers into a
multimedia program.
}
    Notes: {
        12-Oct-2006 Rewrite of colormatch for 64 colors, and bigger handles.
                    Leaping slider handles added.
    }

  1. Here's a minimal version in less than 10 lines:

    random/seed now/time
    view layout [
    b: box black
    btn "Match!" [
    b/color: random 255.255.255
    show b
    r: request-color
    either r = b/color [alert "You win!"][alert join "Sorry: "b/color]
    ]
    ]
