That color looks great on you! If you are just wanting to try something new try lighter and some highlights wouldn't hurt :)

Your current color is very pretty.....I think you could do a soft brown and even more of a reddish brown. Something close to J.Lo's color in the attached pic would be beautiful on you!

Although i like the red hues in your current color, I would really see you with a more caramel tone. I think it would really flatter your coloring as well as your beautiful eyes while providing you softness. You could even add some golden beige highlights to your new color to break it up and add dimension. This color scheme would be great for the summer months to come as it will give off a nice sun kissed feel.

I actually line the tone it is now! But if you are looking for something different you can go a few routes. First you could try dip color! I love the look of that style. Also another suggestion would be big panels of color!
