"Should I wear warm or cool tones?"
I get this question a lot, and the answer is “Whatever the hell you’re in the mood for!!” Makeup is meant to be a fun and creative way to decorate ourselves. So, throw the rules away. Believe that you can wear that shade you’ve been eyeing for ages, but have been too scared to try. Trust me, just about anyone can wear just about any colour, you just have to be willing to experiment a bit, and find the products that really suit YOU. Not all mauves (or corals or fuscias…) are the same. There is almost certainly one for you, regardless of your skin tone.
Personally, my skin does have warm undertones, but it does not mean that I can only wear corals and bronzes. Purples, greys, taupes can absolutely work too. That being said, I do have one consideration when choosing cooler colours, and it’s this: because my skin has quite a lot of yellow in it, cooler tones don’t always show up on my skin the way they look in their tubes/jars. My skin colour adjusts everything a bit warmer. I admit that this can be frustrating, but I just make the necessary adjustments (going cooler and cooler under I achieve my desired look), and off I go, rockin’ that wine-stain like it was designed for me, and me alone! Trial and error comes in to play here, big time, so don’t be afraid to try before you buy (just please wipe off the testers before you let them touch your face. Seriously).
Also, give yourself a chance to get used to something different. Sometimes we get so used to seeing ourselves one way, that it can be uncomfortable accepting that another way might look beautiful too. Changing things up keeps makeup interesting and fun, so play, be willing to take a bit of a risk. You might just see yourself in a whole new way. ;)
