Mini cupcake Rainbow

Every time the issue of a potluck style event occurs, I never know what to bring.  This time I figured, "Hey, why not cupcakes?"  I made the mini cupcakes with the "Funfetti" box mix.  My original idea was to "paint" each cupcake a different color and then artfully arrange the colors into an arc, with sparkly white ends to look like clouds... and then I realized that it would have taken up A LOT more room than I originally allocated.  So, the backup plan was to set the mini cupcakes in a grid like a canvas, and then paint the colors on that way.  I used sprinkles in various colors to outline my rainbow, and color mist to accentuate the arcs.  I spritzed a little extra blue mist above the rainbow to simulate a cloudy sky, and silver sparkles beneath the rainbow (it is a rainbow, after all).  Cake sparkles made it all a little glittery :)
