If you're one of the many women who lighten or change your hair color for summer to freshen up your look, remember that you'll need to update your makeup as well. Hair color accentuates the pink and yellow undertones most of us have in our skin so makeup should be adjusted to play up the most pronounced coloring.

If you're going from a dark blonde to a light blonde look, consider your eyebrows first.

Keep your look natural by lightening your eyebrows about one or two shades. I suggest using Jolen Cream Bleach.

Just mix up the bleach as the directions suggest and paint them on the brows leaving it on for about five to seven minutes. When you wipe the bleach off, your eyebrows will be the perfect shade and your new hair color will look more believable.

You don't want to look too washed out with this lighter hair so use a pink blush to flush the apples of your cheeks with color. Pout Rouge in "Berry Babe" is a great choice.

Finally, play up your new angelic coloring with an iridescent eye shadow. I like N.Y.C. Sparkle Eye Dust in "891 Opal Sparkle" ($3.99). Sweep it across your entire eyelid from lash line to brow bone.

When going from red hair to a more fiery copper, you must again start with your brows.

You may need to pencil in a more intense reddish hue to match your new hair. Feather on Anastasia Perfect Brow Pencil in "Strawburn." If you find that the brow pencil color is not the perfect intensity you need, try this trick: after filling in your brows with the pencil, dip a Q-tip into a shimmering copper eye shadow and lightly sweep it across your eyebrow. The color will be flawless and your brows will sparkle.

When choosing makeup for this coloring, switch to shades that will look radiant with your new warm cast. On lips and cheeks try shades of peach, sheer pinky bronze, golden pinks and coppery corals like Maybelline Shiny-licious Lip Gloss in "Cola Float" ($2.25).

For eyes, use shimmering warm browns, khakis, forest greens and bronzy metallics. For a great khaki-green liner, try Sue Devitt Eye Intensifier Pencil in " Bangladore". A fab copper shadow is MAC Shadow Pigments in "Copper Sparkle" ($19.50).

If you're warming up dark brown locks to a more chocolate hue or with gold highlights, play with warmer tones.

Bronzers will kiss your face with a summer glow so start by sweeping on Physicians Formula Powder Palette Blush in "Healthy Glow Bronzer."

Also try lining your eyes with a bronze metallic eye liner like Bourjois Metallic Eyeliner in "#52 Brun Inoxydable". Wing it out at the ends for a little drama.

If you are taking your grey hair to another level by going silver, think rosy when it comes to makeup.

Use a cool rose-colored lipstick and pick a cheek color like Maybelline Dream Mouse Blush in "4 Mauve" to flush those cheeks. Brush on a taupe or purple eye shadow like Benefit Silky Matte Powder Eye Shadow in "Guess Again" ($2.99) across the eyelid for a soft romantic look. No matter what your complexion, the key is to stay away from warm colors that will work against your coloring.

(Styli-Style Brow Liner 24, $6)

Black mascara will give your eyes incredible contrast and definition, but on the brows use a brow pencil like Styli-Style Brow Liner 24 in "Taupe" to define them -- silver brows would look strange. This specific formula will stay put for 24 hours in heat and humidity.
