To enhance blue eyes I have found on myself that browns, coppers, orangey, and light or medium gold are the best shades for me. I would consider my eyes Probably a medium blue and they can turn green depending what I wear. I have a warm skin tone so I prefer warm colors. as a hi liter under my brows and on the inner eye I will use a frosty ice color or a light gold color for a softer look. Black eyeliner. I’m doing liquid liner at the moment. At first I could not apply it but with a little practice I’m pretty good at it now. I just like the clean bold line and it really makes your eyes stand out.
