LUbuntu (L ubuntu) 20.04 screen/display colour calibration how to?

I recently installed LUbuntu 20.04 (UEFI-GPT) dual boot with Win10. (check screenshot attached).

I’m not able to change the color scheme of my display as I can’t find my graphics card control panel program(Intel Graphics Control Panel/AMD Radeon Software) to do so. My screen in more blue in color..and it’s restraining my eye. I’m not getting natural screen color as I used to get in Win10. (blue tint isn’t visible in screenshot)

Prerequisite : I’m noob in Linux world, I appreciate your help and time.

thankyou
