It is always fun to experiment with haircolor!! I have had mine highlighted and lowlighted for the past 6-8 years or so and that works well for me because the pale blonde highlights get mixed in with the grey Plus having a variety of colors means no roots ever really show - no dividing line - the more colors the better and more natural looking!! Red sounds fun too! My last lowlights were an auburn color and I really like them - gives the hair a chocolatey reddish look without being RED y'now? The only downside is that red colors fade pretty quickly. Will you post pictures when you are done?

GARNIER NUTRISSE NOURISHING MULTI-LIGHTS HAIR COLOR HIGHLIGHTING KIT is a kit I was looking at this week - may try it. The color (I think) was called cinnamon swirl and had a pale auburn in it. Anyway - That kit looked interesting to me. Are you going to do this yourself?
