Re: [csswg-drafts] [css-color-4] Security: handling of color-profiles (#5552)

Color profiles are in practice mostly used to give the (large) amount of measured color information needed to accurately convert colors on a Web page into CMYK for printing on a specific printer/ink/paper combination. The specification recommends some widely used profiles (FOGRA, SWOP) for particular characterised printers, which being standard are less of a tracking risk and will enable accurate printing at a commercial print shop. But if someone needs to print on an unusual printer they can do that too. Such workflows are in practice more likely to be intranet than internet, for example a publishing house generating a printed book from HTML/CSS sources.

Color profiles can be used for RGB colorspaces as well, but the CSS Color 4 specification already predefines the most commonly used ones, so that color profiles do not need to be downloaded.
