Beat 3 minutes more on high speed (scrape side of bowl several times). Divide batter into 3 bowls; add lemon rind and yellow food color to 1 bowl; add orange rind and yellow and red food color to 1 bowl; and add lime rind and green food color to the last bowl. Stir each just to blend. Bake at 350 degrees for 30 minutes. Put layers together with lemon filling; frost top and sides with orange cream frosting. Garnish by placing the walnut halves evenly around the edge of the cake.

Cook until mix thickens and bubbles 1 minute. Remove from heat, stir in 1/3 cup lemon juice and 2 tablespoons butter. Pour into glass bowl; cover with plastic wrap; cool completely. Spread between layers. If there's a store-bought lemon curd that you like, skip this step, and spread the lemon curd between the layers.

5. Beat 1/2 cup butter until soft. Beat in 1 package 10x sugar (sifted) and a dash of salt until all sugar is added. Beat in 2 tablespoon orange juice, 2 tablespoon corn syrup and 2 tablespoon vanilla until spreadable. Tint orange with red and yellow food color. Frost top and sides of cake.
