OMG!  The minor obnoxious gods of the web must have gotten tired of me complaining about card catalogs.  Here's a site that lists hex rgb colors in three different color designation schemes, which you will recognize from the image of the color picker in Pshop.  Not surprisingly, white is 255 and black 000.  Durn.  The second chart down one can hover over all the blacks and find the hex rgb value for several shades of achromatic gray.

Wonders never cease,
