Proper color management



  • It's not 1990 anymore, and we've gone way past sRGB. So can we have proper color management like Firefox has, please? Vivaldi already supports ICC v2 profiles (not v4, but that's not as important). There's one minor flaw: it doesn't regard images without any ICC profile as sRGB, but as being in the monitors full gamut. That leads to pretty big shifts in color for most of the images on the web: http://cameratico.com/tools/web-browser-color-management-test/ (you need a wide-gamut monitor to see the problem). So for a start, can you please consider all un-tagged images as having a sRGB color space, just like the W3C suggests? I've heard there's a command line switch in Chrome to do that (which I shall try in a minute), but having it the default doesn't hurt, does it?

    You should know that Chromium does not handle the profiles correct with the commandline parameter you mentioned.
    You should blame the Chromium code developers for their color profile crap. See https://bugs.chromium.org/p/chromium/issues/list?q=label:Feature-Color-Management

    Vivaldi Technologies devs are not guilty, they can only use this code base!



  • Oh, I didn't blame them. I'm asking them to fix what the Chromium people weren't capable of. I suppose making that change shouldn't be an insurmountable task at all.

    if(img_profile == null) img_profile = "srgb";

    You know? ;)

    Haha. Good joke.
    For your update:

    import brain;
    try { to.think( BEFORE ); }
    catch { shutdown() if !reasonable(); }
    

    Please ask the Vivaldi developers to do do so when they have enough time to spend on.
    Would you be so kind to do this as a Feature Request at https://vivaldi.com/bugreport/ ?



  • Are you trying to be funny or to piss me off?



  • Are you trying to piss everyone off with your demanding attitude?

    This is a new browser, and there's a long list of feature requests and bugs for the team to fix.

    Fixing issues that affect a minority of users is never going to be a high priority while so many major issues need fixing. It may be 2016, but I would like to see some evidence that a significant proportion of hardware bought now is wide gamut. In another thread users are complaining because Windows XP is not going to be supported by future Vivaldi versions.

    Be careful when buying a wide gamut monitor/

    I am colour-blind, so don't care too much as long as the web is not displayed in black and white. From the linked article:

    At the end of the day, unless you are paid to use Adobe software, you’re probably better off with a standard gamut monitor. Websites are designed for standard gamut monitors — they look better in a standard colour space — but there are currently no browsers that do colour management properly (Firefox is close).

    February 2016 update: Firefox now colour manages the HTML canvas, so now only the CSS linear-gradient and radial-gradient boxes are displayed incorrectly (tested with Firefox 43 with Windows 10). Chrome still only manages the colours of images with embedded colour profiles, and IE/Edge still does nothing.

    Oh, only a nonsense reply to your it-is-so-easy-to-program nonsense!
    Dont tell programmers what to to if you dont have a real solution.

    if it would be such short line, done in some minutes to fix the ICC profile problems, Vivaldi would have done and backported to Chromium, trust me.



  • That was a joke, hence the Smiley. You people need to pull the stick out of your behinds…. Jeeez.....

    edit:

    And considering un-tagged images, the fix really can't be much more difficult, because there is already color management built into Chromium as Pesala also mentioned himself. The problem is that Chromium only manages images that contain a profile at all (on Windows at least), but not those without any profile. If they simply handled the latter as if they were sRGB images, that would already be very helpful and shouldn't break the web either (Firefox does it, after all). They'd look the same on monitors with a gamut up to sRGB, but they would also look right for calibrated wide-gamut screens.
    I don't really care about CSS colors for now, but having color managed images would be a big step forward already.

    And you'd be surprised how even mid-range monitors have a wider gamut than sRGB these days. They don't make really crappy panels anymore. With HDR panels already in TVs (even wider DCI gamut and 10bit per color), I think it's time to do something about it in the not too distant future. My TV runs Firefox OS, for example, others run Android and they probably come with Chromium-based browsers.
