The White Balance sliders correct 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 (negative positive values) or more purple (positive 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.
