Following is an RGB Color Selector I created using /View. It is my first /View
creation and I'm pretty happy with it except for a couple of quirks (which are
explained in the "Comments" portion of the header. I have it here if you would
like to use it in determining colors for your /View scripts or HTML pages. If
you can help me fix the couple of problems with the script, I would be
grateful.
Thanks.

Purpose: {
Interpolates and displays RGB color values in tuple and in hexidecimal
based on red, green, and blue sliders.
}
Comment: {
The author is no mathematician and still has not figured out how to make
the tuple range from 0.0.0 to 255.255.255 instead of 1.1.1 to 255.255.255.
Also, the hex values returned have a similar problem, whereas #010101 is
the darkest value instead of #000000. Also, you must slide all color bars
from their original position before clicking on a color frame or else the script
will return an error.
