I really love colorful things, and like to play with color in my makeup as well. I used to think very bright looked ho-ish, but I feel like the average person can totally pull them off if done the right way. Here is what I like to do.
First I line the top lid with the colored liner. I never usually do the bottom lash line because I think it looks weird on me, even with my normal makeup.
Then, using an angled eyeliner brush, I follow the eyeliner with my colored eyeshadow starting from 3/4 in all the way to the outer corner. Near the outer corner, I start making the line thicker and more bold.
Finally, I add the neutral all over the lid, starting from the top down so I don't get green all over my lid. Then I gently brush some over the top of the color to blend the two together and tone it down.
Green and pretty :D.
See, pretty toned down for a bright color, but still green. Totally wearable right!?!
This is a pic of the finished eye, but you can see the eyeliner well here. It's blended nicely, which is why I put it on first.
Now if only I could get mascara on the top of my lashes without getting it all over my skin lol....
