I absolutely love color on my eyes. I love greens, blues and purples, and of course my everyday brown is just a neutral must have that pairs with anything I am wearing. Sometimes though, I want to change it up a little from brown, and give my eyes a little color. What I like to do sometimes is mix eyeshadows. You know how many eyeshados come in quads or threes of similar colors.
I just bought one of these that was a series of three blue colors, all varying in intensity, with the darkest one being a very dark, ink-like blue. You see, when you apply color, you usually don’t want to apply all just one solid color to the whole lid, you usually can use these different shades of the same color to create a little depth and give them intensity without making them look unbalanced to the rest of your face.
It does require a bit of an eye for color, and deciphering balance and correct shading, but with a little practice, you can definitely blend eyeshadows and make them look really cool, making your eyes pop. One of my favorite color combos is actually not in a quad or three pack, but rather just a color combo I came up with when I had already put my subtle brown eyeshadow on that I use every day, and wanted a little more oomph. I ended up combining it with a deep greenish-blue, just swiping it lightly on the crease of my eyelid.
It created a neat effect, and for a little extra drama, I also used a deep, deep blue eyeliner and smudged it. People often think of blue eyeshadow and blue eyeliner as eighties makeup, but if you put it on the right way, it can look really exotic, any time.
I’d say you can probably combine brown with some blues, as long as they are not the shimmery kind, or bright powder blue, and most greens, unless those are also the lighter greens that are more of a pastel. It may also work with plum colors that are warm. Ooh, I think that’ll be my next experiment!
