The true primary colours.

You’re painting with the wrong colour
You were taught that primary colours are those that can’t be made by mixing other colored pigments together, and that all other colors can by produced by blending these primary colors. Red and blue fail on both counts. You can make red by mixing yellow with magenta. While a blend of magenta with cyan yields blue. Meanwhile a massive range of hues are inaccessible if you start with just red, blue and yellow.
Color theorists had this all worked out by the end of the 19th century but for some reason it hasn’t made it to school curriculum's. The proof is in your color printer cartridges. They come in cyan, yellow and magenta, which are the true primary colors.
