I'm going to start with this color group because it is the easiest to explain. If you need to wear Warm colors you are easy to spot and the right colors on you make a very dramatic difference for the better.
Most people who fall into this category have reddish undertones in their hair and muted eye colors. As I said in the "Blank Page" post if the Warm palette is the one for you your skin tends towards golden tones and if your hair has started turning gray that gold cast will also be present in those strands of hair. In other words, your graying hair will look like dirty dishwater instead of silvery white.
In terms of your wardrobe the colors you wear need to be yellow-based and warm. Cold and bright is not for you. Icy blues and pinks make you look like you are coming down with something. Navy blue and black make you look tired and grey makes you sink into the background.
"Yes, yes, but these are all just words." You're probably saying, out loud even. "How about some visuals, please!"
But of course.
Here are the two most important colors in determining whether this is your scene or not.
If you look fab in these then Warm colors are all you. If you look drab then move on immediately.
Here are some more examples that fall into the Warm range of colors.
Notice that browns and burgundys are the neutrals of choice for this group.
I compiled all of these examples using Polyvore.
Are you a Hot Tamale or a Pallid Princess in Warm tones? Do you hate these colors even though they suit you? Do you love them but can't wear them?
