Freeway Daisy from a scanned negative

Just a splash of color in a scanned negative.  This time around used CS5 and just painted a layer.  I don't like the effect as well as a marking pen...lacks that neonish glow and depth one gets when you paint on a negative directly.  Experimentation is half the fun of photography.  I used CS5 to create a layer to color then blended with multiply at 75% strength to get this image.
