We all want to express ourselves with our beauty and fashion choices. However, the main question is, do certain nail colors truly complement your skin tone? Also, how can you strike a balance between trying a nail trend and not looking washed out?
Knowing your undertone answers these questions. A bona fide beauty lover knows the importance of knowing one's undertone when choosing the right shade of makeup products for their skin. The same thing goes for nail colors.
To make your nail design truly shine, choose colors that enhance your skin's natural glow. Understanding skin undertones is the key to selecting shades that will complement both your own look and your client's.
What is an undertone?
All types of skin tones are beautiful and have rich undertones. Warm, cool, and neutral are the classic undertones. Under these undertones are subcategories like light, medium, and dark.
There are five ways to determine your skin's undertone:
1. Vein Check
Determine your undertone by taking a look at the veins on your wrist. If they appear green or bluish, you likely have a neutral undertone. Blue or purple veins indicate a cool undertone, while green or olive veins suggest a warm undertone.
2. White clothing or paper test
Wear any white clothing, or get a piece of white paper and hold it next to your face in bright, natural light. Cool-toned individuals will look rosy or pinkish, while warm-toned leans more yellow. You may have a neutral undertone if you look great in both hues.
3. Look at your facial features
Darker skin tones and darker eye colors may have warmer to neutral undertones. On the other hand, paler skin and lighter eye colors tend to have cool to neutral undertones. We recommend you check out our color analysis article based on the four seasons.
4. See how your skin reacts to the sun
Who doesn't like basking in the sun? Did you know that spending a lot of time under the sun may reveal your skin's undertone? For example, if your skin is burning quickly, it could indicate that you have a cool undertone.
5. Try wearing a jewelry
To find your undertone, compare your skin to the hue of gold or silver jewelry. Gold jewelry is more flattering if your skin tone is warmer; silver jewelry is more suitable if your undertone is cooler.
If you're having a hard time distinguishing whether gold or silver looks better, chances are you're a neutral-undertoned individual. But don't forget that you're allowed to wear any shade of jewelry; it still boils down to preferences.

Things to remember about knowing your undertone:

Before learning about undertones, remember that color perception is a highly personal experience. You can experiment with different hair and cosmetics colors, as well as different nail polish shades, and then combine them. There's nothing wrong with being experimental since you'll learn to know your preference, but knowing your undertone will help you elevate your look.
Just because you have a specific undertone doesn't imply your color choices are limited. Your choice of color expresses who you are as a person. If your personality lends itself to bold and brilliant colors, go for it; if not, go with muted, subtle hues for a more refined appearance. You may also experiment by combining the two.
Be aware that your undertone isn't the same as the hue of your skin without foundation or any other cosmetics. Even people with fair complexion can have warm undertones, and those with darker skin might have cool undertones, depending on their genes.
