A good rule of thumb is to pick colours that don't show up in your eyes to make them stand out. Browns for blue eyes, blues for brown eyes, purples for greens, and pick and choose when you're hazel depending on your strongest colour hints. As someone with changeable eyes, hazel with strong hints of just about everything, I have a lot of colours in my pallets.

Tans are hard...they's super subtle, so they go well on your brow bone to open up your eyes, but you want a slightly darker brown around the actual eye.
