I decided to swatch and water/smudge test all of my colorful eyeliners/eye pencils. I will most likely do this for my black eyeliners as well, but for now, here are the colors so that you can get some use out of the colorful ones while it's still summer! I do have a Battle of the Black Eyeliners, but I didn't test out smudging, I just compared the colors, so CLICK HERE for that.
First Picture : Just Swatches, no primer.
Top to bottom left: Mary Kay Weekender Eye Pencil - Sage, Urban Decay 24/7 Glide-On Shadow Pencil - Clash, Urban Decay 24/7 Glide-On Shadow Pencil - Delinquent, Covergirl Flamed Out Shadow Pencil - Ashen Glow Flame.
Top to bottom middle: Maybelline Master Drama Eyeliner - Taupe Takeover (LE), Maybelline Define-A-Line Eyeliner - Turquoise Shock (LE), Covergirl Liquiline Blast - Lime Green Shade (No Name), Covergirl Liquiline Blast - Cobalt Shade (No Name), Rimmel Scandaleyes Waterproof Kohl Kajal - 006 Deep Blue.Top to bottom right: Urban Decay 24/7 Glide-On Shadow Pencil - Narc, Urban Decay 24/7 Glide-On Eye Pencil - Stash, Stila Kajal Eyeliner - Emerald.
Second Picture: Same shadows with water and slight rubbing.
As you can see, the Mary Kay shadow still has about half of the color payoff, the Covergirl Flamed Out Shadow Pencil is completely gone, the Maybelline Define-A-Line Turquoise eyeliner has slight fading, the Stila Eyeliner has slight smudging, and the rest of the shadows held up very well.
Third Picture: The same test as above, but this time, I patted the water off with a towel.
The majority of the shadows and eyeliners look a lot better now that my hand is dry.
Fourth Picture: I rubbed the shadows with dry fingers so imitate smudging by rubbing your eyes.
As you can see, the Mary Kay Shadow is barely visible, the Turquoise Maybelline shadow, the two Covergirl Liquiline Blasts, the Urban Decay Stash Pencil, and the Stila Kajal in Emerald are barely visible. These shadows don't claim to be waterproof or anything, but I did expect the Urban Decay eyeliner to hold up better to smudging because it claims to be long wearing.
The Maybelline Taupe Takeover eye pencil stood up well in these tests even though it doesn't claim to be long wearing or waterproof.
