Americolor makes a fuchsia gel. You can also get it by making the amount of icing you need using Deep Pink and then make a small amount of Super Red. Mix the red icing into the pink until you have the color you want. Actually until you almost reach the color you want -- it will deepen with time. HTH!
(If it's not quite right you might want to add a teeny bit of purple. It's more bright reddish pink to me.)
