Here are some tips regarding color to keep in mind: light and glimmery colors bring features forward, darker colors make features recede, or go back. So, to make your eyes bold, make sure your lighter color is on the lid and just under the eyebrow. The darker color goes in the crease of the eye, and perhaps a little on the outer corner of your upper lid.
For a little more drama, smudge a little of the darker color under the lower lashes, from outer corner to about midway under the eye. A little eyeliner can add drama, too; I like eyeliners that have a blending tip on one end. The look today is not one hard line, but a smudgy, smoldering effect. I rarely use black eye liner, as I feel it is a little harsh. Smoke, plum, brown are better choices in my opinion.
Of course, mascara completes the look. For evening, I like a fashion look of black mascara on my top lashes, and a plum or midnight blue mascara on my lower lashes. Sometimes Ill tip the ends of my upper lashes with the colored mascara for a fun effect. Its not obvious, but your lashes will catch the light and give those glimpses of color. For daytime, I use a brown/black mascara and sometimes I dont do the lower lashes.
