RE: FS colors; here
PLEASE keep in mind that there are multiple editions of the FS595 - and more importantly, the colors assigned to various numbers are NOT the same between edition. The Semi Gloss OD many of us are fond of is a case in point. If you look at a paint spec dated from a specific year, then look at the FS595 chip applicable at the same time. If you look at a 1961 paint spec, and a FS595B, you may find the same number, but the color may be different (and in the case of semigloss OD - it WILL be different - very different.
Also, with regard to on-line color chips and charts, none of them are right for us. From my work with the publishing industry, I know that monitors must have the colors balanced and adjusted. This is done for the designers at Krause something like weekly. Skeptical? Walk through the computer department and notice the very different shades.
Best wishes,
