As others said, you'll have to watch the feeding order to have the best chance of ending up with your preferred color.

I used a calculator, watched feeding order and got my Mesa Red on my first try. My sister, however, used the same calculator, watched feeding order and got the wrong color TWICE. Turns out there's a tiny bit of RNG involved. She got her Orchard Brown on the third try.

I would say continue to use the calculator and just change the "from color/starting color" if you keep getting unlucky. You should get there eventually!
