Hex color of 20-25% in legend: #FF9233
Hex color of China: #FF8A00

As an aside - for a while now OS X has been shipping with a tool called "DigitalColor Meter" which allows you to see the color at your cursor tip in RGB or Hex. I find it extremely useful for situations like this, as well as the "zoom in" feature to be able to see if there is a border on a particular element, for example.
