What primary pigments would an artist need to mix to obtain a pale yellow green color?
The answer is probably: Yellow with a small bit of blue will make a yellow green. However, this is not going to be “pale” unless it has white added to it as in oil paint, is watered down as in watercolor paint, or is dispersed lightly as in inkjet printing. And, you can get a green from any yellow and any blue. You name two blues, blue and cyan (a green blue). Blue is considered a primary color when you are discussing the color wheel or the basics of color mixing. Although cyan is not a primary color on the color wheel, it is the blue pigment used in any four-color printing process, such as newspapers, magazines, and most home and artprint giclee printers. So, it depends on what kind of color mixing you are doing!
