While working with V-ray Renderer it's often arises the need of using a specific V-Ray map - VRaySky to illuminate the 3d scene. In most cases the standard settings of the map is quite sufficient. But sometimes the color saturation is too high. It gives a strong yellow or blue light. Unfortunately, a combination of ozone and turbidity parameters only, does not always provide the desired result. But as a way out of this situation is the ColorCorrect using. It's enough to put into a ColorCorrect Source slot the VRaySky map and adjust the Saturation value to get the proper illumination.
In practice this is the most flexible way to manage VRaySky illumination.
