No matter how good a display is, the idea of perfect color calibration is subjective – some prefer warmer more saturated colors, while others prefer the calmer cooler side of the color spectrum. It is almost impossible to create a single color calibration that everyone can agree on. The Pixel 2 XL display was specially calibrated with a more realistic color profile in mind.
This more accurate color choice was great for photographers – Pixel phones are famous for their amazing camera capacity. However, this choice of color calibration is typically backbreak due to lack of understanding by the public. Google has then added some new storage color profiles that can be replaced at any time from device display settings.
If you like tinking and adjusting the screen with more refined settings than what can provide a guide will be a treat for you! You can always adjust the screen to make it better or correct to match your personal display performance. Below, I'll take you through the steps you need to start tweaking your monitor and work on creating your own custom color profile.
To access the color tweaks, you must first download a kernel that supports such features. The ElementalX kernel has been a staple to the custom kernel scene for many years now and is a reliable daily driver for all Pixel devices today as well. You can proceed to the main page for Pixel 2 and choose either Android Pie (9) or Android Oreo (8.1.0) based on which OS version you currently have.
If you are not sure which version you are on, enter your settings app and press "System" and then go to "About phone." From then on, you will be able to tell which version of the kernel you need to download under the "Android Version" section. Flashing wrong version of the kernel can create a soft bootloop on your system, which is not an ideal situation in any way!
Step 2: Browse the file in TWRP
If you used the phone to download the file, it should be placed in the "Download" folder by default, unless otherwise specified. If you used your computer, connect a USB cable so that you can transfer the kernel file to the download folder on your phone. Now that you have the correct kernel file downloaded on your phone's internal storage, you can reboot in the TWRP recovery environment.
On the TWRP main menu, touch "Install" and navigate to the "Download" folder where the kernel file has been saved. Touch the kernel file and then "Swipe for confirming Flash" to start installing the kernel of your device.
Now that the kernel is installed on Your system would like you to have access to all the sweets that come with a new custom core. As for this guide, you will focus solely on customizing the color profile for the display. To fine tune the display settings, you must install the official EX Kernel Manager app with flar2 from the Google Play Store.
This is a paid app but it closely integrates all features of the ElementalX kernel with a beautifully stylish interface combined with an auto flash feature that makes the update so easy as possible. If you plan to handle custom core tweaks for all sorts of settings, not just the screen, the purchase is more than worth it as a powerful root tool. In addition, it works with many different custom cores, not just ElementalX. Nevertheless, we have used this core and app combination since the Galaxy Nexus days from 2011 and have not looked back!
Step 4: Grant permissions
Next, open the EX Kernel Manager app, and you should be prompted to provide superuser privileges for the first time. Proceed and press "GRANT" on the popup menu from Magic to access all core tweaks you would ever want!
It would be great to Enter the system settings for your device and press the "Display" section. Press "Advanced" and under the "Color" setting, make sure you use the "Natural" option. It is advisable to do this before making any changes to the EX Kernel Manager app to ensure you start from the original calibration settings.
Now you want to go back to the EX kernel Manager app, and from the main dashboard you want to press the menu button on the left (hamburger menu). Then press "Graphics" and then "Advanced Color Control."
Now that you are on the main screen to calibrate the display, you will be presented with several settings that can be customized to your needs. We will explain each of these below, so you get a better understanding of the effect they have on your monitor.
This option turns your screen into a gray and white mode, which is not usually useful for fine tuning your RGB colors.
Red, green and blue colors all have 256 values. It may have their uses in some cases, but for most, this is an unnecessary option that you can leave. by default and can go all the way down to 0. Adjusting these values increases or decreases the intensity of these colors, resulting in a warmer or cooler display temperature.
Most smartphone manufacturers like turning this number to create the extremely vibrant image colors that we have become accustomed to seeing now. If you set it too low, you can get the "recovered" natural look, while setting it too high, you can create an effect of tan on the colors, especially when it comes to human skin tones. The default value is set to 32.
Adjustment of this setting enables control of the brightness or darkness of the colors shown. This can affect how dark or how easy the RGB colors can be displayed on the screen. If you set it too low, you also make the brightest colors dark, while setting it too high can touch the white balance on the screen. The default value is set to 128.
The relationship between the brightest color and the darkest color. This directly controls how intensive white balance and black balance levels will appear on the display. The default value is 128.
If you have any degree of color blindness, try this setting so that the colors match the way you see certain colors. However, this is a setting that will probably be untouched by most when you customize your personal screen. The default value is set to 0.
