I think they show up pretty darn good considering my eyelashes are jet black. The color shows up but it's not ridiculous looking, which I like. I think I like Black Cherry the best, it's the same color as my hair! :) As a mascara they work pretty well. It's definitely more thickening than lengthening (hence the name "Big Fatty" mascara). I tend to lean more towards lengthening ones since my eyelashes are already pretty thick, just short. I really like these though, and at less than $5 each it was a steal!
Anyone else ever tried these, or any colored mascaras?
