So it lookslike it is purple and yellow although I wouldn't pick colors off a computer monitor typically. Irises incorporate both purple and yellow in a single flower. Gerberas, callas, mums, daylilys, alstormeria, gladiola are also available in purple and yellow. Going with a carnival feeling, you could add orange and fuchsia to the purple and yellow. To get the best price on flowers, you want to use flowers that are in season in your area. What time of year are you getting married?
