You would think that slapping orange and bright red blush on your cheeks would be a surefire way to make yourself look insane, but by some makeup miracle, there are many crazy and weird blush colors out there that actually don't look heinous on your skin. In fact, some colors that you would instinctually throw across the room and set fire to before you would put them on your face, actually look pretty when they are applied. As long as you know which ones to get. Let the following be your guide.
Copper blush is like the halfway point between bronzer and blush. Apply something like NYX's Copper powder blush on the apples of your cheeks and on your temples to look like you weren't scowling in a cubicle all week and actually got outside.
If you're fair-skinned, lilac will show up on your skin as a kind of cool-toned pale pink. It can make you look instantly icy/rude, and for that it's great. MAC Blush in Sketch should do the trick.
If you're tanner (jealous), plums and deep magentas will have the same effect mentioned above. Blush Subtil by Lancôme in Plum Charm works like yeah, a motherfucking charm.
Orange hues tend to warm up your complexion the same way getting a lot of sun, or wearing the correct bronzer, does. Clinique Cheek Pop Blush in Melon Pop has the most annoying name you may ever hear, but the vibrance and life it brings to your otherwise sad and dull face helps you forget that fact.
Red blush can go from 0 to WTF real quick, but if you use a small amount and remain light-handed, it can give you the most natural, didn't-even-try-hard color. Try Exhibit A Blush by Nars, but just make sure to use a large brush when applying—unless you want to appear sunburned, and in that case, you do you (but stay away from me).
