What if you adjusted the green channel brightness settings as well ?
A different green brightness with possible a different gamma value should mathematically get what you need
I don't seem able to get it right by changing the builtin green and gamma settings. Low light levels are a particular problem. I think there is some non linearity in my leds at the bottom end. Maybe I need an adjustable look up table for each bightness value.
We should delete/remove this request as its probably unique to my setup.
What’s your capture device ? Maybe it’s providing inconsistent R G B values
I originally had a UTV007 lightberry but have now changed to a Magewell USB Gen 2
My APA102 LEDS have a gamma offsets between the colours. I.e. the leds follow the same brightness curves but they shifted relative to each other. By shifting the curves in the gamma array by 2 or 3 in the array I can achieve near perfect white light from just on to full brightness. Below is my poor attempt at coding to shift the green curve by 3 in the array. Would be great if someone that knows what they are doing could make a proper delta adjustment to the json config and web.
