To test a new color, select either "Text" or "Background". Then select one of
the 140 color names, or enter a hex value or enter a comma-separated RGB value.
You will notice that in addition to changing the background color, RGB values
entered are converted to hex, and vice-versa.
Also, if you turn off the 'Window Focus' option, then the color sample window
will not get the focus each time you click on a color. Having this option turned
off is helpful if you want to click on one color, and then just use your down-arrow
key to scroll through the colors.
You may also find my color chart helpful when converting
color values between decimal and hexadecimal.
