How to make brown

The majority of the time the chemicals stayed clear, but quite often they created a greenish-brown sludge we assigned the name "Brown". The precise nature of the Brown is unknown, and nobody had the courage (or was gullible enough) to taste or even touch it.

It remains a mystery to this day what this substance was, or even what it was made up of, but a mixture of random chemicals is bound to reproduce the substance known as "Brown".

For example, mixing Red with Orange (the product of Red and Yellow) produces Reddish-orange, not brown. Mixing Blue with Purple (the product of Blue and Red) produces a bluish purple.

If you mix a primary color with the secondary color opposite it on the color wheel, you get brown. Alternately, if you mix all three primary colors, you will also get brown.

For instance, mixing Blue with Orange (which is actually red and yellow) produces brown. Basically, mixing all three primary colors with each other in some fashion will produce brown.

Or a sickly, puke-colored mess.
