Things You'll Need
Paint (red, yellow, brown, plus the original shade of pink)
What you are essentially trying to do, when mixing an orange from a pink, is suppress the pink by adding a warm tone to it. Since pink is nothing more than red mixed with white, you should counteract the white with shades of yellow and extra red. By adding yellow to straight pink, you obtain a salmon or coral color that resembles an orange. For a stronger orange, you must add extra red to the pink mixture.
Note that the results of color mixing depends on the quality of the paint you are using, as well as the type of paint (watercolor, acrylic or oil), so finding the exact color you desire will take experimentation.
Position red and yellow onto your palette next to the pink color that you want to change into orange.
Dip your paintbrush into the red paint.
Mix the red paint on the paintbrush thoroughly with the pink paint until the color is a very rich, red-pink.
Dip your paintbrush into the yellow paint.
Mix the yellow paint with the red-pink color that you created in the center of the palette. The pink should now be an orange color.
Repeat Steps 1 through 5 to intensify the orange color until it is the desired hue.
If you are still struggling with too much pink in the orange you have created, add more red than yellow. Even try adding a touch of brown, to counteract the pink.
