Bright eyeshadow can be tricky, so if you're a newbie turning to brights on your eyes, I recommend using one intense color at a time and using it as an accent (at the outer end of your lid, along the lashline, or in the crease) blended in with a predominately neutral eye (shades of gray or brown make brights way easier to pull off).
Here are my must-have eye makeup additions for spring. Inglot, Nars, and Illamasqua are cruelty-free; I've received conflicting information about Sephora + Pantone Universe since (to my knowledge) Sephora is selling in China.
at Inglot, $14
The brightest periwinkle, begging to be paired with white eyeliner--but only for the bold.
at Inglot $14
A neon salmon, perfect with a faux tan and nude lip. (Despite being called Body Pigment Powder, these are okay for use on the face and eyes.)
at Sephora $26
Part of Sephora + Pantone Universe's 2013 Color of the Year: Emerald collection, this is my personal pick for its unique shade of green (better than the green in the Nars Mad Mad World Eyeshadow Duo), it's crazy intense pigmentation, smooth texture, and ease of bledability. (The pearlescent white gets my vote as a top-notch highlighter, however I was disappointed in the dark blue; the cyan in the Mad Mad World Duo is better than the Bionic blue as far as color saturation, texture, and blendability.)
at Nars $24
Not brown, not red, not orange; a perfect shade for high impact color that's versatile
and super smooth.
at Illamasqua $24.60
The perfect eggshell color in a matte finish; take a look at the moving swatch on Illamasqua's site to see its opacity. Use this as a matte highlighter (so hard to find!) or let it play a more central role for a demure lightening and brightening effect sans color.
