The Layers panel in V-Ray Frame Buffer provides a new powerful workflow for making adjustments to your rendered image. You can bring out render elements and compose them together with individual color corrections in the panel's Composite mode, or deconstruct light contribution in the scene and fine-tune each light individually in the completed render using the VRayLightMix mode. You can also color correct the final render just like you were able to do in the previous version of VFB.

The White Balance (Temperature) slider corrects the colors in the image so that objects that are white appear as pure white (and not tinted blue, yellow, red, etc.) in the final image.
Temperature - Adjusts the white balance of the image by specifying the color temperature in Kelvin. Lower values make the image bluer, higher ones make it more amber.
Magenta - Green tint – Adjusts the white balance of the image to make it greener (positive values) or more purple (negative values).
Color tint – Picks or chooses a color to be the new "white point" for the image, adjusting all colors. Use it to pick a neutral color from the image (e.g. one that should be white or gray).
Render view color picker – Picks a color from the render window. Left-click to choose a new "white point" or a tint to neutralize. Right-click to pick a tint to boost.
