I don't think it's as simple as that with paint because the colours
don't exist in pigment form.

Not sure I understand you here. They exist in ink. I will be happy with
'very close' matches.

IIRC geranium red, sky blue, and
buttercup yellow are the perfect primaries.

Depends on what you need. Physiologically a green hue would also be
included. I want to use the hues defined in HTML as 0/255/255, 255/0/255,
and 255/255/0.

I am quite surprised that there aren't more people who buy pots of these
three colours and try their hand at mixing up what they want

Emulsions are all pastel
shades anyway so, for a start, you can't get black.

Don't know where you get this idea from. Dulux sell emulsions in dark
shades and indeed in black. I don't know how 'pure' a black it is.
