The online color cards are simply photographs (or scanned copies) of the API cards that have been posted online… and yes, there are issues with the color settings of the original camera or scanner (lighting, contrast, etc.), color settings of the recipients computer monitor and color settings of the printer.. if printed. But at least, one can easily tell the difference between 10ppm nitrates (amber to orange) and 40ppm nitrates (reddish) or higher. It would be harder to possibly compare color ranges closer than that with the API nitrate color cards online since the color settings of monitors and printers come into play.
