Why should they have to spend time answering this question? Aren't all of the peaches, pinks, reds and violets in your palette automatically good lip colors for you?
Every color in your palette is a color that harmonizes with your natural coloring somehow.
But not every color will actually look good on your lips.
Your right colors look right because they look natural. So if you wear them in an unnatural way, they won't look right.
Consider my Soft Autumn palette:
Would I wear the greens or blues on my lips? No way. It would look completely unnatural. That goes without saying, right?
Here's me wearing one of my dark purple-browns as a lippie:
But not every peach, pink, red and purple in your palette looks natural on your lips.
This is where many of us -- Winters and Bright Springs in particular -- can get lost.
For example, there are plenty of lipsticks that match Bright Spring's violets.
But a Bright Spring who expects a BSp violet lippy to look natural on her lips may be disappointed. (Soft Autumn's dark purple sure doesn't look natural on my lips!)
It can be tough to know where the line is.
My unnatural-looking brownish- purple isn't really that far away from my natural-looking pink:
It's not too difficult. This post is getting long, so I'll publish the second half, in which I describe how to find the best colors for your lips, next week. :-)
