Well, first: this is not just one color. There are 4 or 5 different colors mixed in the picture. Which makes it hard to pinpoint a name for a single shade. Second: if you know anything about color theory, it is quite obvious that it’s any combination of red and green (or yellow and magenta). In color theory this combinations both can make anything from bright orange to yellow to grapefruit red. Or, if you greatly desaturate it or charge it towards black in hue, to brown. Everyone here is calling it some form of brown as well. And it might actually be browny (the color) by the overall range of values in the picture.

As we all know, brown is just orange with context.
