This is false. Orange is a mixture of the primary colors red and yellow. Brown is produced by mixing red with green, green being a combination of the primary colors blue and yellow.
Are we talking color in terms of light, pigment, or in just base hues?
In light, we deal with a different set of primary colors: Red, green, and blue. Orange exists between red and green, but the true middle point is yellow. Orange resides in the lower range (more red than green) and brown is a matter of saturation. Brown is a matter of saturation. Brown is still a hue of orange.
In terms of pigments, our primaries change once again: Cyan, Yellow, and Magenta. pigments absorb and reflect light in many different ways producing what we experience with our eyes. In the end, it's is still only light, so CMY is only a mirror.
In the the most basic understanding of color the primary colors are red, yellow and blue; these are the colors as of kindergarten. In this way Orange is definitely a mix of red and yellow. More technically, the application of red visual light to yellow pigments. The same effect can be created by the application of red and green light (more red than green as mentioned earlier) on a surface with no (or near none) pigment. Apply the same RG light to a surface with a gray pigment (equal parts CMY) and you'll get brown.
Brown is a part of the orange family.
In 256 bit color schemes:
Orange: R(255), G(~30 to ~254), B(0)
To get brown from orange: R(decrease), G(decrease), B(increase)
The same thing in terms of hue:
Orange: Hue(~5 to ~40), Sat(240), Lum(120)
To get brown from orange: decrease Saturation
So you're right, if you're playing with crayons. less right if you are talking about the physical nature of color itself.
