But hey -- some of us are Autumns. Our colors are earth tones, right? What are we supposed to do?
To resolve this seeming contradiction, we'll first remember that color is always relative. Just because you're an Autumn, it doesn't mean that your colors always look like "earth tones" on you. Next to your Autumny skin, they just look like colors.
So, to avoid looking like you're wearing an entire earth-toned color scheme, just avoid the combinations that create that effect. Google "earth tones" and look at the images: you'll see that the "earth tone" effect is generally created by combining your browns and neutrals with blues and greens -- basically, earth and sky. Occasionally you'll add some yellow or red for accent. All of this worn together reads as "earth toned."
Wear just your blues, or just your blacks and whites, or just your pinks and purples, and you definitely won't have an earth-toned effect, even if your colors are coming from that "earthy" Autumn palette.
The reverse of this is true as well: if you're a Natural, and your Style ID calls for earth-toned color schemes, combine your greens, browns, blues and neutrals together and you'll create an appropriate effect -- even if your palette is objectively cool:
Next to True Winter skin, this kind of palette will look plenty earthy. :-)
