Ok, here's how this works. Post the country's name and the colour of the notes that are in use in that country.
I'll start you all off.
New Zealand: $5 - Orange, $10 - Blue, $20 - Green, $50 - Purple, $100 - Red.
USA: $1 - whatever - green lol .... I guess we have little variety on that heh
Actually Starfox, the U.S. bills are traditionally green, but newer versions of the $5, $10, $20 have more colorful faces ^_^
;D well...Scotland: £1 = green, £5 = kinda blueish £10 = we have many £10 notes and each have different colors, there's blue, purple, greyish and kinda violet one too. £20 = deep purple lol
