Color on the Web Community Group

Discussion forum between CSS experts, Color Management experts, and TV/Movie/Broadcast experts to explore use cases and inform W3C specification work (such as CSS Color 4 and subsequent levels). Both SDR and HDR are in scope. Wide gamut displays and the Web is in scope. Web use of ICC (v.4 and ICCMax) is in scope.

Note: Community Groups are proposed and run by the community. Although W3C hosts these conversations, the groups do not necessarily represent the views of the W3C Membership or staff.

Interest in TPAC meeting to discuss SDR/HDR compositing issues

Is there any interest in meeting to discuss use cases and issues involved in compositing a mix of SDR and HDR elements: images, graphics and video? Examples would include maintaining the color levels of sRGB elements when a HDR video begins playback, subtitle levels on HDR video, mixing of sRGB and HDR images on a page and css support for HDR.

I have requested the 15:30 to 17:30 time slot on Tuesday 7 November in the community group room at TPAC for a possible discussion session among interested parties. (Many time slots had already been allocated so I went ahead and secured one before the where gone.)

Welcome

Welcome to the Color on the Web Community Group. It was created to allow color experts from various fields – traditional print-oriented color management, display experts, content creators from the TV, broadcast and film industries, CSS and graphics experts, and other interested parties – to come together, share ideas, use cases, experiences and discuss technical solutions to improve the state of Color on the Web.

Particular areas of interest include, but are not limited to:

  • Unambiguous, colorimetric color specification of desired presentation
  • Wide gamut colorspaces (wider than sRGB)
  • High dynamic range (greater range of luminance, darker blacks and peak whites greater than paper white)
  • Color matching between media (raster images, video, vector graphics) and text/styling content (styled by CSS)
  • Consistency and predictability of display
