Feature request: Adjustable color palettes for the Apple II's 16 colors #11

It would be awesome to be able to tweak the individual colors for each of the 16 decoded colors in the config utility. I notice the selection of the "red" and "brown" are not to what I remember as a kid. Of course we're talking about "NTSC" which we all know is highly variable based on the phase of the signal coming from the Apple II (Adjustable with the variable capacitor right on the motherboard) and the tint control on the monitor.

I like the idea. Changing individual colors isn't quite so trivial as it sounds though, due to the tricks how the firmware generates the DVI protocol data.

But the latest firmware now has three different color profiles to pick from. New option in the configuration menu: https://github.com/ThorstenBr/A2DVI-Firmware/releases/tag/v1.5 image

I may add a few more profiles with future versions.

Specifically, I'm also looking for proper RGB values of the Euro-machines. These had a proper encoder to generate a PAL signal, and were not relying on artifact colors. Would be nice to add a PAL RGB profile, but haven't found a good/reliable source yet.
