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: orange paint absorbs the wavelengths it is not reflecting, brown absorbs its own set, and rust 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 orange and brown make?
Orange and Brown make rust, #c26100. 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 brown. 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 orange than brown?
Three parts orange to one part brown gives orange. Reversing it to one part orange and three parts brown gives rust 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.
