I absolutely love the direction this has gone. I think it's a quantum leap in usability. 👍
I think we can tighten up some of the code reuse though taking advantage of implicit casting. I'm happy to make those changes.

This is all so much nicer! 😍

shouldn't these implicit operators be on the Pixel type instead of Color? there are alot more Pixel types after all.

Colorstruct with a hidden internal hi-res representation, that is convertible to all pixel typesColor.BlackorColor.WebSafePalette)Colortype now.Coloron all public API-s (Consequence:PaletteQuantizer<TPixel>has been dropped.)ReadOnlyMemory<T>on public API-s instead ofT[]QuantizedFrame<T>.GetPixelSpan()returnsReadOnlySpan<T>. Populating the span is an implementation detail. IntroduceIQuantizedFrame<T>to maintain clean abstractions here.ColorBuilder<T>.FromRGBA()toFromRgbaConsequence on our terminlogy
Color ≠ Pixel any longer. Color is a general term, pixel is a representation drawable on an
