most issues edited. computed value of system colors split out into issue 28, since I think it's wrong.

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 management 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.”

no edit in CSS3-color.

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 :

IEC 61966-2-1: 1999: Multimedia systems and equipment — Colour measurement and management — Part 2-1: Colour management — Default RGB colour space — sRGB, International Electrotechnical Commission, 1999. ISBN 2-8318-4989-6 as amended by Amendment A1:2003. Available at http://webstore.iec.ch/webstore/webstore.nsf/artnum/025408 and at http://www.colour.org/tc8-05/Docs/colorspace/61966-2-1.pdf .

Where the first part of the text up to and including “sRGB,” (without the comma) links to: http://www.colour.org/tc8-05/Docs/colorspace/61966-2-1.pdf

Status
updated the shared bibliography for the CSS specs accordingly.
