This is one of my favorite summer looks to do. I call it the "citrus eye" because the orange and yellow together remind me of yummy citrus fruits.
To do this look I used the NYX palette called Shangri-a, which contains a yellow, peach, and orange eyeshadow.
I started with the light yellow in the inner corner and worked it to the middle of my eye. Then I used the dark orange in the outer counter and blended it to the middle as well. I blended the two together so there were no harsh lines. To ensure seamless blending I used a little of the peach color on top of where the two met. I then used a light brown by MAC called Texture in the crease for a little extra definition.
