From cymbolism:
a dedicated website that aims to quantify the association between colors & words, making it simple for designers to choose the “best” colors for the desired emotional effect. Cymbolism allows visitors to associate one color for a given word, in order to to track these relationships over time in form of frequency strips.
The color of money is definitely mostly green and a bit gold (paper versus hard asset). The other colors are probably from non-US residents.
