Over the last two years, I have experimented more with nail color than at any other point in my life. If you think about it, trying on all of the colors of the rainbow in nail polish is a great way to express your mood of the moment — inexpensively.

And right now, I am passionate about purple!

Thanks to Chanel, here is yet another fabulous color to add to your nail polish drawer — Paradoxal. This gray violet color has iridescent specs that shine in a irresistible way.

I happened upon this color before it hit the shelves, by mistake albeit. While getting a pedicure, the nail technician used a UV topcoat over OPI's You Don't Know Jacques that turned it this shade of purple (minus the iridescence). It was an amazing color that I never could duplicate, so I was thrilled when Chanel read my mind. Absolutely perfect to get me in the FW10 mood!

After wearing out green for spring, I've moved onto the neutrals — and I'm testing quite a few. I tried a khaki color a few weeks ago on both my fingernails and toes, which was pretty cool. However, what I really wanted was more of a putty color. Enter: essie.

When I came across essie's chinchilly, a medium gray color, I immediately fell in love. It's the perfect neutral ... as close to putty as I'm going to get. It goes with everything in my wardrobe, so it eliminates potential outfit challenges. A nail polish staple.

While I partake in pedicures quite a bit, I am not one to paint my fingernails often. Yet with this color, I've been painting and repainting endlessly. That's how great a color this is.

As it turns out, the big nail colors for spring are beige tones and pale pinks. Between beige, gray and pale pink, I see an opportunity for some great tone-on-tone outfits. Go for it!

A couple of weeks ago I received one of the best pedicures I have ever had. In keeping with the excitement of it all, I decided to take a departure from my normal color (red). So, I went with OPI’s Lincoln Park After Dark (dark purple). I liked it at first, simply because it was so different for me. However, after a few days, I thought that perhaps it was a better color for fingers versus toes. And then after a week, it just needed to go. It made me feel a bit Halloweenish, or even goth. In circumstances such as these, I wish that making a quick color change was as easy as waving a magic wand. Don’t you know that in the not-too-far-off future, it just may be.

A team of chemists at the University of California recently identified a way to change pigments in a liquid. Made of the iron oxides commonly found in mineral make-up, the polymer-embedded pigments can be instantaneously and reversibly manipulated by a magnetic field. In other words, the nail polish that goes on pink could be shifted to a new shade - say burgundy, charcoal or beige - and back again when exposed to a variable magnetic force. Conceivably, the technology could work on any liquid cosmetic made with iron oxide pigments, including lip gloss, foundation and more. Just imagine.

Because we are not there yet, it gives me the excuse to go out and get another phenomenal pedicure by Jane. This time, I’m going pewter. Hey, if I don’t like it, another pedicure is in order, right?
