Color profiles included in digikam package are provided as you can find them 
on the Internet and no developer nor contributor have worked to build these 
ones. Specifically you can find sRGB profile at Internet Color Consortium 
homepage [http://www.color.org/sRGB.html], just as all its specifications, 
history, etc.
