2)  If G gain is less than 172, Increase G gain by up to 
172,  and  then  increase  R  gain  and  G  gain  same 
amount of increasing G gain. 
3)  If R gain or B gain is over 255, readjust G gain less 
than 172, Conform to R gain is 255 or B gain is 255 
     Medium / Warm Mode - Fix the one of R/G/B gain to
