Just putting this out here but in a color camera instead of having a RGBG or what have you instead you have a RYYB bayer matrix, I looked it up and it does exist in small camera's for certain phone but i’m wonder if it would be viable for a larger size sensor due to yellow filter allowing more light in than green filter which in turn gives more signal. I might be wrong i that like to hear thoughts bout this
RYYB bayer matrix viability for larger astronomy camera sensors
I'm waiting for this guy. If they ever perfect it, it will be fantastic:

As far as I recall, Sigma tried Foveon sensors but had issues with getting all 3 colors at the same F number. Noise profiles were all over the place for G and R. Also amp glow in G and R was an issue.
I was looking at this:

Interesting concept. Imagine some form of LSHO grid with 10nm band passes…
Really the VHS verses BetaMax thing. The most practical technology wins, not the best technology. Actually the frequency with depth is used to a certain extent in current sensors. Chips that have extended IR responce like my QHY5iii715c have deeper wells that allow greater sensitivity on longer wavelengths.
