How to calibrate android screen ?

As you probably know, android phones have bad habit to be brutally over-saturated. Do someone know ANY way how to set phone's gamma, contrast and color saturation ? I'm hobby artist and this is very important for my work. I have Lenovo A7000 with root. Someone must know it. After all, all those values must be stored somewhere as variables. Even if i must enter values via console.
Thanks
