"I’ve made a colour palette for 16K/48K/+ machines, based on the YUV voltage tables in Chris Smith’s book The ZX Spectrum ULA.

This colour palette is suitable for ZX Spectrum 16K, ZX Spectrum 48K and ZX Spectrum+ machines, basically machines which use the original Sinclair Ferranti ULA, 5C102E, 5C112E or 6C001E. It is not suitable for 128/+2/+3/+2A machines, as these use a TEA2000 composite video encoder and don’t have the YUV voltages in Chris Smith’s book.
