Color Theory Primary Colors

I used Cotman Turquoise ( I had an old tube-still good as new), Pyrrole Scarlet and Cad medium Yellow. I always have trouble with creating purple unless I use magenta or Quin Rose, So I added some Quin Rose to get a purple in the background which I added after the fact.Its all good. Nice practice. I started out with Scarlet lake but wasn't happy with the mixes. Then used Pyrrole Scarlet.
