</div>It has nothing to do with display colorspace, but with the color space where<br>
the operation are computed. And if you had read that page you would notice the<br>
author is interested in actual real-world images, but the best way to<br>

So what are the "enormous amount of problems to our users" ?</blockquote><div><br></div><div>scRGB is linear. Most.. well, all the labs use 2.2 or 1.6. Most of the monitors in the web are calibrated to 1.6-2.2. And not every software pays any attention to embedded color-profiles, e.g. browsers.</div>
<div><br></div><div>This means that you must convert an image to sRGB before publishing in web. Are you going to inform every user about that?</div><div><br></div><div>Second. During this conversion you will loose most of the colors of your image. You remember that 80% of scRGB colors are imaginary, don't you? You have to use special techniques to workaround non-gamut-colors. Thanks to these "techniques" you image may become darker/whiter. Are you still going to explain this to every user who opened Krita for the first time?</div>
<div><br></div></div><div>Third. You must use 16 bit or float for scRGB. Do you think degrading performance twice worth an ability to work with 80% imaginary colors?</div><br>-- <br>Dmitry Kazakov<br>
