Masking objects from the Sun in Unity? Everything is getting a ugly yellow hue.

We are creating a environment in Unity ( for a mobile game) and the sun is creating a ugly yellow hue that is washing out objects. We have these white wood pieces in the environment that do not look white at all, they look yellow when the sun is on. It is possible to mask objects in Unity so they retain their color with the sun on ?

I mean, change the color of the sun? OR what is typically done, is you add some sort of ambient / GI with a slight blue tint (from the sky), which makes the sun's slight yellow look whiter.

Which Render pipeline are you using?

Also a screenshot would help understand better what you're talking about.
