DIY tablet computer, maybe.

What a waste of fuel and daylight. Went all about looking for syringes with blunt needles. Doing a google search suggested that vape shops stock them since people use them for refilling and mixing their liquids, but nowhere actually had them in stock. Tried to find a medical supply store but looking now I went to the wrong place, a first aid training company, that was closed. Still trying to figure out how I made that mistake. I thought I knew where it was.

I did pick up the paints though. Tried mixing them close enough by hand to the proportions I imagined would work and came out with a very neutral grey instead of a deep salmon red. I think it's gonna require more thought and reading.
Mixing half and half of cyan and yellow yields the colour i'd expect. Mixing a third (in total) of white to that yields about a 50% yellow and cyan each (on the colour sliders in this program). But trying to mix in black really throws it off. Of course these arent accurately metered portions, and while i'm aware they wont be a complete match i'd expect them to be close enough to recognise.
Searching about finds alot of angry message board people yelling about the guy asking the question not understanding how printers work then proceeding to explain something separate to what the guy asked, which is a common theme on those stack exchange type websites.

Have you tried a pharmacy for syringes I’m not sure you need needles but they have them too.

That's so obvious and I just... never considered it. I'll take a look tomorrow. I got some 10ml syringes ordered from amazon but i'd like to get some 1ml ones for easier hand mixing without wasting alot of paint. Thanks for the suggestion.

Done a bunch more searching and found nothing but nonsense. Plenty of people are asking this question and it seems if they ask computer people they get basic explanations of colourspaces, and even more esotetic explanations of stuff like how the eye evolved (???) but they don't answer the actual question. And if they ask art people they get a bunch of people saying 'learn to mix colours the old fashioned way! Dedicate your life to learning this redundant skill!'
So thinking about it myself. I figure if it's 100% magenta then thats 100% of the magenta obscuring the white underneath (or maybe more like 90% in reality to not soak the paper). And if there's 50% cyan on top of that then theres still no white in that. But if its 50% magenta and 50% cyan then thats 50% of the white showing through, so the white is the percentage left over from the largest percentage of any colour.
But then printer inks are transparent and not opaque, so even if it was 100% magenta then some of the white will be showing through. Maybe. But either way that gives me something to test tomorrow, and maybe gets me in the ballpark where I can calibrate out quirks in the medium. Assuming i'm correct at all.
I also feel that since colour perception is relative to their surroundings then i'm more worried about their relations than total accuracy, for now at least. If I end up with something that has more or less contrast or a different gamma curve (or whatever you'd call the reflective equivalent) than whats on the display (in ideal lighting) then I think that'd be entirely satisfactory as long as the colours relate.
