I just can't seem to get the color matched, not even close. When I try to darken the red, it just turns brown. No good.
I'm going to look into some other water based paints, like Tempera, to see if they will work. I read some stuff online that says any type of water based paint should work with latex, so I will give it a try. Not sure if that is true, but I'm at the end of my rope with the Burman pigments.
