>>3012998you are misinformed. it's not about that the diods in the array would influence each other, but - as I said (maybe next time read better) - the problem is that the diods can not cut the spectrum exactly.
let's say you scene a blue backdrop with a red cube in front and the cube fills a third of the picture. the red diods gather the red light, the blue the blue. ok. since red is quite "far" away from blue (see a chart of the optical elecromagnetic spectrum for reference) blue will be quite blue in the result as well as red red.
but what if the cube is green? green is closer to blue and what then happens is, that the blue diods react not only to the blue but also a little to the green light. (just as red diods also react to infra-red [NIR] for example).
this little light "bleeding" will cause that the blue will be shifted in tone when setting the WB to get the precise green.
you can easily test my statement yourself. you will see that the same backdrop shifts tone when another colour is prominent, and you adjust to that colour is precise.
alternatively you could think before you talk. up to you.
