Not only is the numbering system a great idea, but with Avon's True Color technology each color is vibrant and pigmented instead of 50 shades of chalk. This was important for me because I like my color to not look ashy.
The "jewel tone" is a look I use often. Turquoise is one of my favorite colors so Avon's Eye shadow Quad in Glow Teal is my favorite palette in the entire collection. To get the look just follow the numbers. I like to start with color #1, which is usually the lighter color, in the inner corner of the eyelid (alternatively on the brow bone) and work towards the outer corner ending with color #4. Be sure to blend the edges between the colors well! Finish up with a black eyeliner like Avon's Always On Point Eye Liner and a black mascara like my favorite Avon's Mega Effects Mascara.
