All but the white colored countries take part in the "Afro". 
light green: country does not take part in any other (african ) single currency
dark green: country uses already the CFA-Franc
dark blue: country will take part in the planned "Eco"
light blue: country uses South African rand besides the own currency

South Sudan and the insular states Mauritius, Comoros, Cape Verde and Seychelles are missing on the map. Seychelles do not take part in the "Afro".
