Please see http://lists.w3.org/Archives/Public/public-html/2010Mar/0144.html
for a discussion on HTML5 and color management. 
Also,
http://lists.w3.org/Archives/Public/public-canvas-api/2009OctDec/0001.html for
a discussion on color management and drawing images to canvas.

WRT "and the result displayed in sRGB color space (approximately gamma 2.2)"
from the bug title:

Based on data we collected some time ago, sRGB set as the display profile on
~70% of Windows PCs; the other 30% have a (non-sRGB) monitor-appropriate
profile assigned via Windows Update (most common) or the user calibration (less
common)

It would be more useful to define a working color space for canvas elements to
clarify canvas element color management.
