Here's a try on Omni, the option "C" will probably be fotkat in bright light ... 
This option is corrected for xda - wherever it uses getOffsetForIndex it is equal to the number set in the settings (for omni = 100) ... 
option "B":

but while digging through the code - I was looking for my jamb, I saw that this parameter is used in several places of code and not everywhere it affects the color, in another place of code it affects on the brightness of the final photo (and if you set = 100 brightness is very high), in this regard, made another option - 100 is substituted I'm only there where it affects the color of the final photo ... 
option "C":

In general, that's all the option that I can offer.
