Note that the red test image is only valid for iOS devices, since in Android you can see the Instagram logo even though it doesn't support wide color

I can't see the Instagram logo in the red test image on Windows 7

On Windows, I can see the logo on one of my screens, but not the other.

Yes, was a bit confused when I opened the image on my ancient work computer (Windows, old Dell monitor) and could see the logo clearly. Interestingly, Chrome refused to display the image despite it nominally being a PNG, and I had to open it via an external program. Dragging the window to my second monitor (different model) causes the logo to vanish (though I do feel like I see it for a split second on the second monitor... optical illusion?).

  Chrome should be able to display it fine. The dl=1 param on the Dropbox URL means the request is served with a response header indicating it's a download. Change the link to dl=0 and it won't force the download.

By the way, anyone who can display it (all my nice monitors aren't with me at the moment) can you see it on this imgur link? http://i.imgur.com/qCna54M.png http://i.imgur.com/qCna54M.png

      I can see the logo on the imgur link on my TouchBar MBP
    - TD-Linux 10y ago
      That doesn't work - that gets you Dropbox's resized and recompressed version, which breaks the effect (likely it strips the ICC profile)
    - lisivka 10y ago
      I can see logo in downloaded png at every screen I have, including old 2008 Acer. Never screens display it better, older screens need to be tilted.

      I can see the logo just fine on the imgur link, but I can't see the original in firefox or in GIMP. I wonder if it has to do with imgur compressing the image, or maybe approximating/ignoring the colorspace as was mentioned above.
    - gcr 10y ago
      There's something weird happening. imgur shows straight red on my 2015 Macbook Pro, but my iPhone 7 shows the logo. The dropbox thumbnail link (with ?dl=0) shows the logo. Opening the link with ?dl=1 in Preview shows straight red. I think Dropbox is doing some weird thumbnail processing.

  You are probably seeing the color management of monitor 1 in effect on monitor 2 while the window is less than halfway. Once it goes above half then monitor 2's color management takes over fully and it disappears.

Can't see the logo on OSX Sierra on my 2014 MacBook Pro Retina 13in.

  Can see on my 2016 MBP Touchbar 15" w/Sierra
- jeffamcgee 10y ago
  I have a 2016 MBP w/ touchbar, and depending on which color display profile I select in System Preferences, sometimes I can see it, and other times I can't.
- tunaoftheland 10y ago
  I couldn't either on my MBP late 2013 until I changed the Display Profile to "Display P3". There are other profiles that will show the logo, too, like "Adobe RGB (1998)"
  - eridius 10y ago
    If you change your display profile like this you're going to have incorrect color rendering, so don't forget to change it back after you've had your fun looking at the (inaccurately-rendered) image.
- eridius 10y ago
  I don't think that computer has a wide-color display. The 2016 MBP should (at least, the one with the touchbar, not sure about the one without), and the retina iMac supports it as well.
yefim 10y ago
Do you know why that is the case? Do Android devices project the Display P3 color space into the sRGB color space?
- yincrash 10y ago
  https://www.reddit.com/r/Android/comments/52ultq/does_you_android_device_have_wide_color_check_here/ https://www.reddit.com/r/Android/comments/52ultq/does_you_an... This comment explains it (at least for Webkit's test image, which is probably similar to Instagram's). > No, it is a bad test. It is an image with an ICC tag that indicates it uses a color space larger than sRGB. The image data has the logo using color that should be outside the sRGB color space, but it still uses 8 or 16 bits to store that data. Android doesn't have color management. Android basically assumes all images are sRGB, so you see the logo. iOS does have color management. iOS sees the ICC profile and interprets the image data so that if you do not have a display that could show you the different reds in the image, it doesn't display them. So we have everyone in this thread on Android thinking they have a wide color display. Most of their displays aren't even 100% sRGB. My Nexus 4 shows the logo. It is very much not a wide-color display.
  - mikeyk 10y ago
    I used the same approach as the Webkit image, so the same applies here, too (it's also why we only serve Display P3 photos to iOS clients with wide color screens, most Android devices would treat them incorrectly)
    - yincrash 10y ago
      Thanks for the confirmation!
- therealmarv 10y ago
  No. There is absolutely no color management in Android. https://code.google.com/p/android/issues/detail?id=225281 https://code.google.com/p/android/issues/detail?id=225281

mikeyk 10y ago
Good to know--I didn't run it through my Pixel. Some devices will do a relative projection from Display P3 to sRGB, which means that it will look "relatively" like it would in Display P3 but projected onto the sRGB color space. Edited to add: and some other ones are doing something even less fancy, which is just to ignore the color profile entirely and just assume sRGB and display it incorrectly, taking for example what would have been the maximum red point for Display-P3 and making it the maximum red point in sRGB.
- bostand 10y ago
  Since you brought up your Pixel: what is the point of adding something 1% of your customers maybe can see instead fixing that horrible horrible compression that makes uploads from android (80% world wide market share) look like crap? (Not an android user, I just want to figure out how a company of your size prioritises between bugs and features.)
  - jrowley 10y ago
    I can't speak for OP but say this does effect 1% of users today, what percentage does it effect in 6 months, or a year? Not bad to be proactive. And regarding android compression issues, although resources are always finite, I imagine in this case the android team is fairly separate, so they may very well be working on that compression issue while iOS is pushing forward into new terrain.

Windows I can see it if using XnView but I can't see it if I use the built in image viewers. It's an older computer so it's XnView converting to sRGB most likely.
