You're welcome to disagree, of course. But I recommend you do some research into how sensors and sensor firmware works.
The best way to imagine a pixel is a bucket, the more light it gets the more the bucket fills up. If it doesn't get any light it's black (unexposed), if it get's filled up it's completely exposed. The firmware then dictates that this particular pixel is a red one (or a green one or a blue one) and the storage device records it as being a half-full bucket of red light. The hues are achieved by clumping the surrounding different colour receptors (pixels). The sensor array is sensitive to light only, not colour. It's the firmware that decides which wavelengths to 'filter' out to each individual pixel. It's really not hard to imagine forcing the firmware to apply a cast (alter the wavelength) to any part or, all of the array.
As I pointed out before, that's exactly what you do when you change the white balance. You can shoot indoors with the WB set to Tungsten, or you can leave it on Daylight and stick a 80B filter on the front of your lens. The effect is the same. All we're postulating here is instead of having half-a-dozen WB settings, let's have a few hundred - then have an additional setup which allows these to be graduated, spotted, coned, heart-shaped or whatever you want.
The day you think you've found perfection is the day you stop looking, then someone else will find it and move in front of you.
