About color temperatures:
There are many different shades that are considered to be “white” for various purposes. One of the 
common methods of representing white color is known as the “color temperature”. A white color with a 
low color temperature appears to be reddish white. A white color with a high color temperature appears 
to have more blue in it. The SET USER COLOR TEMP menu allows you to alter the color temperature 
and the overall color balance of the image by adjusting the red, green and blue gains and biases.
To make the color temperature higher
Set the value of B GAIN (or B BIAS) greater, and the value of R GAIN (or R BIAS) smaller.
To make the color temperature lower
