William and Kate Wedding: 4/1 Queen’s Hat Will Be Yellow

You could hit it big should you wager that Queen Elizabeth II have a black hat atop her head when her grandson Prince William weds Kate Middleton on April 29 at Westminster Abbey.

Of all the colors, black is the longest of shots: coming in at 20/1, according to the odds set by Irish bookmaker Paddy Power.

Yellow, light blue, purple and pink are the favorites at 4/1, 9/2, 11/2 and 6/1, respectively.

As for the color of Kate’s wedding dress, ivory leads the way at 4/6. However, those who bet on a brown bridal gown might be able to retire should they call it right. The odds for that are 66/1.
