Warm = Yellowy-beige-gold based lip colours
Cool = Blue-red based lip colours
Majority of the people say that warm lip colours complement warm skin tones better and cool lip colours compliment cool skin tones better. However, in my opinion this theory only works best with choosing foundation colours and that's it. Everything else differs on different individuals and you should try and figure out which tones suit you best.
Now I really do not know the science behind what suits which skin tones but in my experience,
Warm lip colours against Warm skin tones usually clash
This is because everything appears too much in symmetry and it makes the look flat as nothing stands out in particular.
I am wearing a warm peachy-nude lip colour below. As it has a lot of yellow in it and my skin is warm-toned(yellow undertones) as well, it makes me look a bit lifeless and dull in my opinion.
Having said that, it does not mean I cannot wear peachy-nude lip shades at all, yellow-toned lip colours like below just do not flatter me very well and I find them hard to pull off. It just means I need to find a cooler toned peachy-nude colour that compliments my skin tone better.
It brings out the 'yellow' in me! yikes :S
I used Sleek's True Colour Lipstick in Barely There above. It has a sheen to it and is quite comfortable to wear and does not slide off the lips. Not a very unique shade but if you're a fan of such everyday colours then you'll like this one for sure.
Below I am wearing a blue-toned bright pink and although it's a loud colour to pull off, you might see how it lifts my face slightly and makes me look a bit more lively. It adds dimension to my face and as it's contrasting to my skin tone, it makes the lips stand out.
Such colours albeit bright, are easy for me to pull off due to their cool undertone as they tone down the yellow undertones in my complexion
Above I am wearing Sleek's True Colour Lipstick in Amped which is a matte shade. If your lips are well moisturised and exfoliated, this will glide on like a dream, otherwise it will exaggerate dry areas. It is intensely pigmented and even after wearing off, leaves a nice stain to the lips which I love. I am in LOVE with this shade ♥ I like their matte range of lipsticks much better than any other of their finishes.
But that's how it works for me. It might be totally the opposite for you, so give it a try ladies, compare your pictures wearing different lip colours and see what suits you best. A fun experiment for a boring day at home eh?
In both the looks above, I am wearing Sleek's Pan Tao Blush, which I believe is still available to purchase. Now some people hated this one classifying it as an 'orange' blusher. However that is slightly misleading as according to me its a bright peach and is perfect for the spring! It's pretty easy to pull on in fact and is such a unique colour.
Apologies for the overdose of Sleek posts but I am sure you guys do not mind as it's quite an affordable brand and available easily. I have a lot of their products lying around and the lovely weather unconsciously diverts me towards them.
