The best color palettes for daytime makeup looks will always depend slightly on your own personal coloring and style preferences. That being said, there are some basic, one size fits all rules for most women to look their best during the day. The goal is to create a look that is natural, effortless look, rather than the intense, smoldering look that works better for evening events and parties.
Avoid eye makeup that is too severe or smoky. Jet black eyeliner is fine for night, but for day use grey, plum, brown, or dark blue/green instead, as this is less striking and generally more appropriate for work or class than the harsher jet black.
Use natural/neutral tones for your eyeshadow, rather than bright, dramatic colors. Pale pastel peaches and browns add definition to the eye without looking like you're trying too hard.
If you are pale skinned or blonde, you may want to opt for a brown mascara instead of black, as this is softer for a daytime makeup.
Highly saturated shades of red or purple are too intense for daytime. Opt for a sheer gloss, or lipsticks in pale pink, coral, peach, or rose tones. A little sparkle will play nicely off the daytime sun, but don't go overboard. A lip gloss or lip balm with some added SPF benefits will help to keep your lips healthy and prevent sunburn if you plan to spend a lot of time in the sun during the daytime hours.
A daytime look shouldn't involve too much foundation or powder, as this can look cakey or wear off as you perspire. However, a touch of pale rose or light orangey-pink bronzer adds a healthy glow to your skin, as can a light application of bronzer over your whole face. Make sure to pick a shade that's complimentary to your natural skin tone, however, or you will look unnatural and uneven.
