How to determine your skin tone?
There are two basic skin tones -- cool and warm. You can decide what you are by investigating the color of your veins as seen on the underside of your arm. If the veins show through blue, you've got blue or white undertones, meaning you're a cool skin tone.
How to choose the Right Foundation for your skin tone?
When shopping for foundation, particularly if you need foundation for sensitive skin, always start with a small test patch (at the jaw) to determine if your skin tone matches the given product.
By matching your skin tone with the right season, you'll be able to dress your best. Winter skin tones can be pale, yellow, or dark with blue or pink undertones. Sharp colors like black and blue are great for winter skin tones, but light browns won't help you out, so give them a wide berth.
How do I know if my undertones match my skin color?
Observe your jaw line (it’s usually less affected by color changes than the rest of your face) to find your surface color; remember, the jaw is where you need to blend, so this is the shade you need to match! If silver complements your skin better than gold, you likely have cool undertones.

Matching beauty demands to skin tone...
Determining Your Skin Tone. The first step in your quest for complementary clothing colors is to identify what type of skin tone you have. Naturally, this will seem like a bit of a no-brainer at first, but it could be trickier to work out if you’re somewhere in between.
Pale Skin
If you’re prone to freckles, get burnt to a crisp at the mere mention of a sunny day and don’t ever really tan at all then it’s likely you have pale or fair skin.
Light Skin
Skin that is light-ish in color yet tans relatively easily without burning falls into this camp. The good news is you have lots of options. But there are still a few considerations to be made.
Olive Skin
You may make others envious with your natural, year-round glow but there are still certain colors that you’ll want to swerve if you’re to stay looking your best.
