Yes, there is a particular type of profile called a named color profile, which is what I was referring to above. Instead of a set of curves and chromaticities (for an RGB profile) or a set of Lab measurements of CMKY swatches (i.e a 4D lookup table, for a CMYK profile), it consists of a one dimensional list of names (strings) and colors in Lab or XYZ. http://www.colorwiki.com/wiki/The_7_ICC_Profile_Types#Named_Color_Profiles For an earlier run at specifying this, see https://www.w3.org/TR/2014/WD-SVG2-20140211/color.html#named (note that SVG required an explicit sRGB fallback each time, which is not needed here because CSS can express a fallback in the usual way). -- Best regards, Chris Lilley Technical Director, W3C Interaction Domain
