After "accurately" capturing the NES composite video signal and creating a palette, I felt that the resulting image could use some seasoning of sorts. While I enjoy the FCEUX palette, it can be a little too vibrant with a number of titles in the NES library. I took the opportunity to create a "Hybrid" palette - an interpolation between my NESCAP and the FCEUX palettes. The results of this palette give a best of both worlds colors. Even the purple-ish sky in Super Mario Bros. retains some of it's purple-ish without going too deep into saturated sky blue. Keep in mind that the color temperature and other settings on your display heavily influence the perceived color as well as the viewer's vision system (eyes and brains!).
