white-balance adjust .
1. Setting the color temp.
A. 6500K color
Warm color temp. parameter is x=313±30 ， y=329±30
B. 7300K color
Normal color temp. parameter is x=301±30
，
y=317±30
C. 9300K color
Cool color temp. parameter is x=283±30
，
y=297±30
D. sRGB color:
sRGB color temp. parameter is x=313±30
，
y=329±30
