Similarly to [[RedIndexBlueIndex red and blue]], there's just something about red and green that catches most people's attention. Red and green traffic lights, red and green {{Christmas| Tropes}} colors, redheads with green eyes, [[Franchise/SuperMarioBros Mario and Luigi]], etc. In much of the world, this ''is'' also red and blue, particularly where UsefulNotes/GreenIsBlue.

This contrast is {{averted}} in the 1 out of 8 men and 1 out of 200 women who are red-green [[http://en.wikipedia.org/wiki/Red-green_colorblind colorblind]], and neither color is distinguishable from [[TheYellowIndex yellow]] either.

Red (or similar orange) and green are popular colors to contrast on national flags, often alongside neutral colors (such as [[TropesInWhite white]] or [[TropesInBlack black]]) or with in-between color [[TheYellowIndex yellow]].

Yellow is, in fact, the color created when red and green are combined in the light-based RGB color space. But if you try to combine red and green paints, you get [[ThisIndexIsBrown brown]].
