If you are an autumn, your undertones are typically golden, with skin coloring in shades like peach, beige and golden brown. Red, red-brown, dark blonde and rich brown or brown-black hair shades are common for this season. Autumns also tend to have darker eye colors. That's the difference between you and Springs. Simple. I only just now worked out I'm a Spring, my eyes are blue.
Autumns look wonderful in rich neutrals, earth-toned and spicy colors. Consider olive, forest or mossy greens, orange shades, grays, dark browns, burgundy, purples and camel and rich beige colors.
