Very little of a mix is ever half and half. Shifting the balance moves the result along the range between the two colours.

Why it works
Pigment mixes subtractively: yellow paint absorbs the wavelengths it is not reflecting, green absorbs its own set, and lime 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 yellow and green make?
Yellow and Green make lime, #80d41a. 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 tan. Add black for a shade, which gives olive. 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 yellow than green?
Three parts yellow to one part green gives lime. Reversing it to one part yellow and three parts green gives emerald 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.
