I Love browns or purples on blue eyes I personally love Bobbi Brown's Long-Wear Cream Shadow in Heather, Benefit cosmetics Creaseless Cream Shadow/Liner in Get Figgy a brownish purple, my favorite is Too faced's eye shadow duo in Totally toasted but unfortunately the color was discontinued( if you search it it's the one pictured) Also I'd suggest staying away from blue. I know many people like blue on blue eyes but I feel that the bright color overpowers your eye.
Hope it helped!
There are a number of different colors that particularly make blue eyes pop. We actually carry palettes that cater to individuals with blue eyes. I would highly recommend trying any of them out in order to really enhance and make those blue eyes of yours sparkle!
