Are you looking to be able to mix the colour you're aiming for a little more easily or for a method to help with repeating mixes?
If you use paints that come in a dropper bottle (or transfer to them if they don't) you can tap out dots of paint onto the palette as a rough form of measurement. With artists' paints I've done the same thing with the open ends of tubes for many years. Because different paints vary in consistency it's sometimes not that accurate - with tubes or bottles - but if they are around the same viscosity it's not a bad start.
Of the ones I've seen recommended, there really isn't a measurement system that's workable for very small volumes of paint because of the large margin for error - anything that relies on forming dots or blobs of paint will naturally have a degree of variation. The importance of this varies from paint to paint, range to range; with some colours your could be out by as much as 10% on one or two of the ingredients without a huge difference (you'll still have a colour in the right ballpark) but with others less than a 1% error might give the wrong hue entirely.
I don't know anyone who does this but you could transfer paints to syringes with wide-bore needles and use them to squeeze out measured 'ribbons' of paint against a scale, but honestly it doesn't seem worth the effort.
