There are many ways to determine your undertone. Here are the most commonly used methods to understand if you have cool or warm undertones. 

Vein Test: 

Take a moment to inspect the veins on your wrist. Are they leaning toward blue or purple? If so, cool undertones might suit you best. If they sway towards green, you likely have warm undertones. 

Silver vs. Gold Jewelry: 

Admire yourself in the mirror with both silver and gold jewelry. If silver jewelry lights up your features and complements your skin tone, it suggests cool undertones. If gold jewelry enhances your features and looks flattering on your skin, it indicates warm undertones.

Eye & Hair Color: 

Observe your natural eye and hair color, if you have blue, gray, or green eyes paired with black, brown, or ash blonde locks, then chances are you have cool undertones. 

Warm undertones often team up with brown, hazel, or amber eyes and hair colors like red, golden blonde, or warm brown. 

When you choose makeup, clothing, and accessories that align with your undertones, you are likely to create a harmonious and balanced look that complements your skin tone. This understanding can contribute to a sense of comfort in your own personal style.

Remember, these tests are just guides, not strict rules. Feel free to mix and match based on what makes you feel empowered.
