The Autumn color palette is warm and rich.
To help you determine your personal color palette, refer to this post which includes a handy flowchart to eliminate guessing!
If you are an Autumn that means you have a warm skin tone and hair that is typically darker than medium brown.
You have a lot of depth to your coloring with golden undertones including a warm undertone to your skin. You may have peachy skin, which is a warm type of pink.
You have a deep, earth tone quality to your eye color such as black-brown, deep to medium brown, bright brown, deep green, light to dark hazel, dark blue, mixed blue and green eyes with gray or/and yellow in them.
In general, your coloring is low in contrast but not as delicate as Spring and Summer. Some Autumns have a high contrast coloring but not as vivid as a Winter.
A light, muted but rich coloring which appears mousy and a mix of both cool and warm tone might make you look neutral. But you still have some depth of color with an overall deep and warm look.
