Color Calibration is the process of measuring and adjusting the color response on your display so as to reach a common standard.

Different phones have different screens that are deployed through different manufacturers. If they are subjected to a comparison, the color reproduction of one phone may vary from another.

Color Parameters

Every person has a unique inclination towards certain colors, hues, saturation and levels of backs & whites. Therefore, the degree of likeness one manifests from certain contents in screen may depend on their screen color profiles.

But we are not stuck. Each color parameter on your phone can specifically be adjusted in pursuance to reach your preference. Here is how you do it: –

Requirements

A rooted phone
A custom kernel
Kernel Adiutor App, download here

Preparing Your Device

Step 1: Install a Custom kernel

For this method to work, you need to have a custom kernel installed on your device. Most custom kernels these days have KCAL support which lets you tweak the color profiles. So, it is mandatory to flash a custom kernel before we set forward.

If you are on a Custom Rom, you may already have KCAL support.

Step 2: Install Kernel Adiutor App

Kernel Adiutor is an app that lets you manage kernel parameters of your phone. Even though the app is currently discontinued from playstore, it works as fine. We will modify our screen profile through this app.

Step 3: Grant Root Permission

Once you have installed the app, it will ask for your root permission. Based on Magisk or SuperSU you have installed, you need to grant the root permissions.

Applying Color Profiles

Step 1: Go to Screen Settings

Once the app is opened, go to hamburger menu at the left and open screen settings: ≡ → Screen

You will see a set of features which you can tweak individually to obtain your desired color reproduction.

Step 2: Apply on Boot

Before you set out, you can see a toggle to apply settings on boot. Doing this, the app will apply the screen settings every time your phone boots.

If you are unfamiliar with all the nifty settings, here is the list of color profiles and their corresponding values.

(Be sure to take a screenshot of default values before you make any changes so that you can reset it whenever you want.)

Parting Words

Color preference, as your taste, is very unique. I hope you can find a profile that tones with your preference; if you do not, I suggest you to play with values until it best matches your liking. This article was inspired from one of XDA forums, find more color profiles at XDA.

Having said that, I would suggest you to stick with the most standard color settings, primarily, if you edit photos/videos from your smartphone. The color tones you may be seeing on your phone can be utterly different when you view it on other devices. Being on standard/balanced colors is the most efficient way to go.
