If out of specification then fine-tune factory "CLR_TEMP_R/
CLR_TEMP_G/CLR_TEMP_B" for Normal temperature.Other
modes pls. refer to below form (for reference).
Remark:a,b,c,d are offset refer to Normal dada and build in
firmware to close warm x=0.314, y=0.324
and Cool x=0.285,y=0.293 as posible.If out of x,y in warm/cool
define tolerance 0.015 then fine-tune the offset value is
needed.
