Therefore when adding additional colorants to an existing formula, the hue of your white can move a completely different direction than the colorant added; its called "crossing the color wheel" which cannot be corrected by additional colorants; the only fix is starting over with a new mix. Example: if the white formula includes yellow and then you add blue (to make the white "bluer") the white becomes "greener" not "bluer" (blue and yellow make green). The best option in this example is to leave the yellow out of the formula and add blue if needed. Hope this brief "color theory" is helpful.

Exactly! This is why one learns to really look at "white" in the sunlight - if you're good, you eventually start seeing the colors in it. Takes some practice . . . and you waste a bit of paint/toner in the learning process.
