How to adjust and set the contrast color of vivo mobile phone

If this means setting the camera contrast color:

Contrast color is a kind of filter. The camera that comes with the phone doesn't have this filter, so you can enter the camera-click? Three-ring icon, and then select the effect you like.

If the display color of the mobile phone is reversed:

When color inversion is turned on, the actual display color will be inverted. For example, black will turn into white, and viewing photos will have a negative effect.

Go to Settings-Quick and Auxiliary/More Settings-Auxiliary Function/Auxiliary Function-Color Reversal-and turn on the switch.

Note: The purpose of color inversion is to enhance the contrast of the displayed content, so that people with poor recognition ability for low-contrast content can clearly distinguish it.

Otherwise, you can enter the online customer service of vivo official website-click on mine and enter "Manual" to contact the online customer service for processing.
