Determining your skin undertone for your makeup

Hello all you beautiful people...
Have you ever had an experience with foundation looking fake on your skin, lipstick looking dull or gaudy or your jewellery looking flat on you????
Well, I think I know why... You are most likely wearing makeup with contrasting Undertone to your skin...
Now you would ask " ये  undertone किस चिडीयाका नाम है??"
Well, your skin is a certain shade and then it has a certain undertone... ie. warm undertone, cool undertone or neutral....
If you've seen certain foundations of the more expensive variety, they have these things on their shade numbers.. I know you have seen W2, N4, C5 and wondered what that is...The letter is the undertone and the number is the shade. (MAC has an exact opposite way to numbering, so ask their sales executives). Mostly, the girls at the counter here in India have no experience and try to just sell their product instead of helping you determine your undertone and shade perfectly.
So how do you find out your undertone? Thankfully, there are a few ways... Look at the inside of your wrist. Do you see all those veins? What colour are they? Green, blue or do you see both the colours? What colour of jewellery complements you? Golden,  silver or both...  If your veins look blue and silver complements you, you are a cool toned girl... Your undertones are pink, blue or red. If your veins look green, gold jewellery makes you look like a princess,  then you are a warm toned gal and your undertones are yellow, golden or peach... And if your veins are a mix of green and blue and you can rock any kind of jewellery,  well, you are a neutral toned gal...

Even if you are a cool toned girl or a guy, buy neutral or warm foundation as these do not oxidise so easily and blend better with your skin... 

You can apply the same principle to your other makeup items like lipsticks or glosses, blushes, bronzers, etc.. Cool toned people can rock cosmetics with pink undertones and warm toned people can rock cosmetics with yellow or peach undertones.. Neutral toned people are just lucky, aren't you? 

Well, all the best..

These L'Oreal foundations are all the same shade but the one on extreme left is w3, the middle one is N3 and the one on the right is C3.
