How many ICC profiles will we alias? Do you have a set in mind that “developers want to specify”? If I want to specify colors with the color profile of my specific monitor, how I will do so? If I want to specify colors that match a specific printer's output, how will I do that? I'm saying that any single particular color, even if it's outside sRGB, should be specifiable without browser support for downloading and processing ICC color profiles. If you have a particular need to convert a set of numerical descriptions of colors (described according to a particular ICC profile) on the client into a form accepted by the browser, it seems like you could do it with a javascript library -- and, further, if there were substantial demand for such a feature, examples of such javascript libraries and how they behave should be being raised in this discussion. The issue that seems important to solve in this thread is to make sure we agree on how we want colors outside of the sRGB gamut to be specified in CSS. -David -- 𝄞 L.
