Why it works
Pigment mixes subtractively: green paint absorbs the wavelengths it is not reflecting, grey absorbs its own set, and emerald is what neither of them absorbed. This is why paint behaves differently from a screen, where light adds together instead.
Frequently asked questions
What color do green and grey make?
Green and Grey make emerald, #438d5a. Mixed in equal parts that is the result you get with paint, ink or any other pigment.
How do I make the result lighter or darker?
Add white for a tint - here that gives sage. Add black for a shade, which gives green. Add white a little at a time, because it takes far less than people expect to shift a mix.
What happens if I use more green than grey?
Three parts green to one part grey gives emerald. Reversing it to one part green and three parts grey gives slate grey instead.
Does this work the same way on a screen?
No. Screens mix light additively, so red and green light make yellow there. These results are subtractive - paint, ink, dye and pigment - which is what people mean when they ask what two colours make.
