Bobbi Brown Denim Ink Is more Navy Blue and has silver glitters in it, where as MAC Waveline is between navy blue and purple, Denim is almost black on the second swatch but MAC Denim Ink is still in between dark blue, navy, purple something in between.
Both are pretty easy to use, they all work as an eye shadow.
I applied few coats on Both Bobbi Brown and MAC to be able to give you the exact shade.
Both look same on the eye as it looks same in the pot,
I sometimes applied dark blue eye shadow, pigments, glitters over them and looks really nice.
It looks fantastic on brown and hazel eyes.
I do not recommend this on blue, green eyes , they need a shade to pop their eyes.
