You mean like this? I think this is kind of what you meant…
(I’m not even joking when I say that this is how Battletoads actually looked for a lot of people, including myself.)

I think that right now, you might be in a similar boat to how I was this past Christmas when I finally had all three things–an NES, an EverDrive, and a 1995 Toshiba CE20D10. No matter how much I messed with CRT shaders, the Grade shader, Composite signal shaders, and NES palettes (though this affects all consoles, not just NES), nothing ever looked similar enough to my real CRT. After several months, the things that ultimately solved that for me were just these two things. If you get these two things from almost any consumer TV, you can get close to that TV’s colors:
- The NTSC color correction axes. Grade doesn’t support this. In my case, they were in the TA8867AN chip’s data sheet. Instead of buying my TV’s service manual for ~$10 USD, I just looked through my CRT’s vents using my phone’s flashlight and found the chip that way, and I searched online for its data sheet.
- The TV’s white point, which I took by carefully eyeballing and averaging the top row of my NES’s palette on the 240p test suite. If I were rich, I would’ve used a colorimeter instead. I assume most TVs tried to be as close to the correct white as possible, but the white would drift as the TV kept being used.
This is my alternative grade shader that I’m going to be posting in a separate thread after I get some sleep. I’m hoping this will work better for you than just tweaking tint settings. Instead, you can set the composite demodulator axes (or pick from several known ones), the white point, and the consumer’s contast, brightness (black level), color (saturation), and tint (hue rotation)… and then of course you can append color-mangler to get back to the tint settings you’re used to, because no matter how much science and math you do, things never look right anyway. There’s phosphor simulation too, but it’s not worth the trouble at all; you should just stick to sRGB. https://www.mediafire.com/file/koimav7yj0l607t/consumer-color.slang/file https://www.mediafire.com/file/lf9mpb25jzp9llm/trincolor-jul-6.tar.gz/file
