Status : spec edited

URL : minutes of CSS meeting, 2008-10-20, morning session: http://lists.w3.org/Archives/Public/www-style/2008Nov/0023.html

Issue 26

Summary : add mechanism for migrating to being conformant to the part of the spec that says CSS colors are in sRGB

Raised by : David Baron, Beth Dakin

URL : minutes of F2F meeting, 2009-11-03 (have resolution)

Resolution : updated: do this in CSS4-color instead: “RESOLUTION: re-add a ‘color-correction’ property with the two values ‘default’ and ‘srgb’”, “‘default’: what UA would do if the property weren’t specified at all. That can change over time. (E.g., at the moment we (Safari/Webkit) don’t do color managament at all. But we may do so in the future.)”, “‘srgb’: All colors are presumed to be defined in the sRGB color space unless a more precise embedded profile is specified within content data. For images that do have a profile built into their data, that profile is used. For images that do not have a profile, the sRGB profile is used so that the colors in these images can be kept “in synch” with the colors specified in CSS and HTML.”

Status : no edit in CSS3-color.

Summary : sRGB reference needs to be updated, check other references too

Raised by : Chris Lilley

Reporters response to resolution : http://lists.w3.org/Archives/Public/www-style/2010Oct/0070.html

Proposed Resolution : update them. Note: When I (Tantek) last asked Chris Lilley about what should we update the [SRGB] reference to, he said we should use the same reference as the latest SVG.

From http://www.w3.org/TR/SVG/refs.html :
