2 weeks ago If you want to support several shapes, there are 3 sets that can easily be handled with the same converter as they provide the same colors and just need a chars lookup table change: Squares: ⬛⬜🟥🟧🟨🟩🟦🟪🟫, they are in Unicode 12.0, but be aware that the first two might not look the same as the rest of the set in some fonts, or even render as monochrome symbols instead of Emojis. Circles: ⚫⚪🔴🟠🟡🟢🔵🟣🟤, they are in Unicode 12.0, and again the first two might look different. Hearts: 🖤🤍❤️🧡💛💚💙💜🤎, this set is in Unicode 12.0 and should render as consistent color Emojis in all fonts.
And then there is the better but less supported one: Hearts (extended): 🖤🩶🤍❤️🧡💛💚💙🩵💜🤎🩷, this set is nicer as it provides 12 colors instead of 9 and the lighter gray and blue really help for many images, but it requires Unicode 15.0, so it should probably be a separate explicit choice.

@PhMajerus suggested color emoji/glyph support in #201. Especially the various color hearts are interesting. This requires:
ChafaSymbolMapto import multicolor glyphs.CHAFA_SYMBOL_TAG_EMOJI,CHAFA_SYMBOL_TAG_HEARTS, or something like that.We could seize the opportunity to allow monochrome glyphs to be represented this way too (as grayscale coverage), using bigger 16x16 pixmaps for matching, then employ it automatically at high work factors to maximize quality.
