Just because all table salt doesn't come from the same place on the
earth, isn't purified in the same factory, isn't all boxed by the same
manufacturer, doesn't mean you can't be fairly sure it will taste about
the same when you put it in your stew, and that it will taste quite
different from, say, red pepper. A particular pigment, with a particular
number, has a particular chemical composition and as a result,
particular properties and characteristics. There are very few
manufacturers and purveyors of pigments in the world; the difference
between a particular pigment from one manufacturer or another is like
the difference between table salt labeled with the Morton's brand and
table salt with some other brand name on it, whereas the difference
between different pigments is like the difference between table salt and
red pepper. As to all the fillers and extenders and whatnots, you find
those more in the student grades and other lesser types of paint; most
fine artist quality paints have little or none of this gunk in them and
tend to be pure gum and pigment, sometimes with honey added to retain
moisture, but otherwise no extra stuff.
