An advantage of the primitive hardware that ties the TIA directly to the task of composite video generation is an unexpectedly large colour palette: 128 colours in its native NTSC. This is because each 7-bit colour selection is converted directly to a 4-bit phase offset applied to the colour subcarrier and a 3-bit amplitude applied to the luminance output, allowing two very cheap bits of electronics to produce a wide range of colours at the cost of those colours being dictated by the mathematics rather than by any human judgement.
