Subtle ways of warming up the skin:
1) Add a little red to your eyebrow color (brownish red, chestnut,etc)
2) Add a little bright orange to the lower eye line along with a brownish red liner (use eyeshadow to keep it soft)
3) Add a brownish red eyeshadow to the crease of your eye.
4) Warm up cheeks with a combination of a pink (hot pink) and orange (bright orange) cheeks (blend very well).
