That's the most varied features I have ever seen in one app.
Well, basically, the color picker.

The Galaxy S4 has a good screen but it's a little too over-saturated giving unnatural skin tones. Switching to "Movie" mode results in rather muted colors. For accurate color reproduction there's a new app "Calibrated photo Viewer" on Google Play with pre-calibrated color and gamma corrections to show photos in their natural colors.

Adobe RGB and sRGB color spaces are supported so both standard and professional photos can be viewed seamlessly, without the need to switch 'screen modes'.
The app works just like a normal photo viewer. No rooting is required.

Added color balance controls
I have added controls for custom fine tuning of color balance, to allow for variations between different S4 devices.

I'll check it out, thanks! I'd love a way to set the rgb for the whole phone, not iust one app, as my whites are quite greenish in comparison to many other screens-is this possible without kernel modifications?
Unfortunately I don't think that is possible without a mod kernel.
Check out the new version with Auto Color Balance.
Use a camera on an external android device as a color measuring device.
No more fiddling with color controls.
The two devices communicate via Bluetooth.

If you're colorblind, please disregard this thread. Rate this thread to express how you deem the color saturation and accuracy of the OnePlus 2's display. A higher rating indicates that you think that color accuracy is very high and saturation is excellent.
Then, drop a comment if you have anything to add!
Anandtech frowns on the greys

According to Anandtech the accuracy of colour is not very good, especially in the greyscale range. Also, he says that it is a little too blue even otherwise. Does anyone here have any different opinions?
(Can't post the link here yet)
Color saturation is very poor, as I have switched from Xiaomi Mi4 it looks as if colors are washed off.
The stock calibration is too bleak for my taste. I added a little more contrast and saturation. It's android after all
Coming from the Galaxy Note 2 and LG G3, I'd say the colors are great. Not insane like on Galaxy phones though, but much better than on LG G3. For blue/red, the color temperature is settable even on the stock OxygenOS. It appeared too warm at first, so I sent the dial almost all the way to "cool" to get what seemed like a correct white color.
I had note4 and oneplue 2 color saturation is very bad.
Using Boeffla kernel I managed to get this display almost perfect concerning whitebalance and colors.
How about lets see some display settings you guys used to improve color/image quality
I find the screen too cool (I came from a s6 which i found too warm).
Would love to see some settings too.

for me by far, the best display is Samsung AT&T Captivate, no phone had reached my expectations until now. I'm satisfied with OnePlus 2. I would be happy if someone shared KCAL settings.
Hi i'd like to have a screen like Samsung Phones with good saturation and good contrast. How can I do for changing those option(If I need boeffla kernel how can I configure the app for having à magnific screen?)
(I haven't installed yet but I will do it soon)
Thanks
As a happy owner of a x-rite ColorMunki, I've managed to find the time to run some tests on the phone screen and find a suitable configuration for Boeffla Kernel's color settings.
First, some values for the un-calibrated display, with the default configuration (rgb 255, saturation 255, hue 0, display value 255, contrast 255) and maximum brightness:
Black level = 0.2751 cd/m^2
50% level = 122.72 cd/m^2
White level = 578.07 cd/m^2 (quite close to the 600 cd/m^2 that OnePlus claims)
Approx. gamma = 2.24
Contrast ratio = 2101:1 (am I mistaken or OnePlus claimed "only" 1500:1??)
White chromaticity coordinates 0.2896, 0.3019
White Correlated Color Temperature = 8532K
Gamut coverage: 90.1% sRGB (not great)... http : // imgur. com /wb8kylH ... sorry but I can't post proper links yet.
Extremely "cold" color setting, with a quite remarkable contrast ratio and decent brightness. I'm quite impressed by this display!
To achieve a D65 (6500K) whitepoint and 2.2 gamma, as per sRGB standards, I've used the following settings:
red: 255
green: 233
blue: 159
saturation: 255
hue: 0
display value: 260 (it basically affects the gamma)
contrast: 255
resulting in:
Black level = 0.2804 cd/m^2 (shouldn't change)
50% level = 122.72 cd/m^2 (dictated by the gamma)
White level = 517.92 cd/m^2 (lost some brightness, unavoidable)
Approx. gamma = 2.19 (much closer to 2.2)
Contrast ratio = 1847:1 (I can live with that!)
White chromaticity coordinates 0.3121, 0.3288
White Correlated Color Temperature = 6540K
In my opinion, increasing the saturation above 255 is counter-productive, as it will only result in clipping. Furthermore, the vast majority of media content (unless you're working with professional Adobe RGB-based workflows) has most likely been designed for sRGB devices - or at least something with comparable gamut coverage. AMOLEDs are exceptional in terms of "color richness", but might result - if not properly calibrated - in unrealistic over-saturated colors.
The side-effect of these settings is the appearance of banding in images with blue gradients, such as... blue skies. I'm afraid, though, that this can't be solved in any way.
Cheers

Ive tried these settings and it just made my screen really yellow and warm, I still prefer using the "extreme amoled" setting listed in AK's kernel thread.

Well, all displays differ physically... but most importantly it's a matter of personal preference.
Personally, I am accustomed to the "yellow and warm" display (I'd find the default settings way too cold and blue ) as it matches every other screen that I have around me, and I find it appropriate to rely on an industry-standard color space/calibration. At this point, I can blame the content creator (i.e. whoever took the picture/drew the image) for not using sufficient saturation .

I am using your screen value, contract and saturation setting though, it makes a change from the extreme amoled look but using opposite colours, R:235,G:245,B:256. I prefer cooler/whiter looking screen i guess haha.
Rooted, flashed boeffla kernel, installed boeffla app and adjusted color, saturation and gamma. Looks better than any other 1080p for me now.

AK kernel thread is closed as the developer switched phones but if you go onto the thread over at original development AK kernel and look at post 2, there's a list of kcal settings.

I was wondering what are the best settings for display in terms of color gamut and image enhancements
should it be set on professional RGB or standrad or super vivid, also should what ever is chosen run with image enhancements or not?
keep in mind, my goal is realistic colors yet not so dull
on profession RGB mode, it looks sharp but its not colorful its dull, doesnt look as realistic also
standard mode looks good to me, but ive seen people having issues with it if enabling image enhancements...
super vivid, some people argue and advise to stay away from it as it not realistic at all, but it does bring out the colors,
so my question is to really understanding people with knowladge about these things, which settings are best for the most realistic colors and sharpness
thanks
