[time-nuts] OT: Hewlett Packard paint codes

[Jack Hudler]

This assumes you have a calibrated scanner and a calibrated printer.
I don't have an IT8.7 target or its equivalent to calibrate the scanner.

Perhaps I should start there.... heck I'll just try and match it by eye.

If you are doing this in Photoshop it's a simple task. First, load the image
of the original scan. Then on your floating toolbar click the left color box
(foreground color), that will open the color picker box. Put your mouse
pointer over the unknown color in the image and left click. Just make sure
you don't have the "only web colors" checked. That color picker box will
then show the RGB values as well as the hex value.
