-<guilabel>Color Temperature</guilabel> is a simplified way to characterize the \
spectral properties of a light source. While in reality the color of light is \
determined by how much each point on the spectral curve contributes to its output, \
the result can still be summarized on a linear scale. This value is useful eg. for \
determining the correct the white balance in digital photography, and for specifying \
the right light source types in architectural lighting design. Note, however, that \
light sources of the same color (metamers) can vary widely in the quality of light \
emitted. Low <guilabel>Color Temperature</guilabel> implies more yellow-red light \
while high color temperature implies more blue light. Daylight has a rather low color \
temperature near dawn, and a higher one during the day. Therefore it can be useful to \
install an electrical lighting system that can supply cooler light to supplement \
daylight when needed, and fill in with warmer light at night. This also correlat es \
with human feelings towards the warm colors of light coming from candles or an open \
fireplace at night. Standard unit for color temperature is Kelvin (K). \

-<guilabel>White Balance Saturation Indicator</guilabel> option can be enabled only \
when <guilabel>Over Exposure Indicator</guilabel> option is on. This option adds up \
the colors if more than one channel in a pixel is over-saturated, and you will see \
the combined color resulting of White Color Balance controls settings. This rule is \
applying to target preview area and haven't effect to final rendering. \
