Artistic practice has proved that adding a little yellow to magenta can set off scarlet, but scarlet can't set off magenta. Adding a small amount of magenta to green can get blue, while blue and white can get dark blue. More colors can be mixed with yellow, magenta and cyan, which are pure and bright.
Adding other colors to pure red pigment can change the hue of red. You can choose most primary colors and secondary colors, and each color can bring different effects when mixed with red. Big red can be matched with purple and blue, yellow and green, and many other colors.
Color matching skills:
By mixing red with orange in the secondary color, you can get orange red, but the amount of orange cannot exceed red, otherwise the color will be more like orange. The same is true for the color matching with purple. As long as the amount of red is more than purple, it will bring out purple-toned red, but if there is more purple, it will become purple.
Adding a little blue to red can set off purple, but if you add too much blue, it will turn purple.
Adding another secondary color green to red, red and green are complementary colors, that is, they are in opposite positions on the color circle, so adding green to red will bring out a brownish red. Don't overdo it, or it will bring out brown or putty.
