Pilot has a consistent color and flow along the line

The green color in particular is awesome

Perfect color, no skips, no smearing, no cutting into paper, etc.

these do not bleed like older wet designs have--fast drying-these smear very, very little (red and purple tends to smear more than the other colors, for whatever reason FYI)--durable ink-this ink holds up better over time than older generation gel/rollerballs have and resists fading from UV light super well--colors-blue, black, green, and red all use colors that are easy on the eyes, give good contrast, and aren’t ugly

I like how they are small enough to make writing neat, but just big enough so that you can appreciate the nice ink color that flows smoothly from these pens

All other colors seem fine.

Not the most long lasting pen but outstanding color pay off

Like other gel pens, the ink in the G2 doesn't last very long but the beautiful colors and easy flowing ink make them a worthwhile purchase

The different colors are just as vibrant and write just as smoothly as the standard black pens

The colors look great, and there is no quality degradation often seen in competitors red and esp, green

Great for people with small writing to better distinguish one letter from another, and all the colors make color-coding organization easy!

They are excellent pens, with solid color

Nice additional color other than black

They glide easliy and the color is dark

Great for small writingToo thin to smudge!Cons:Not too dark, they are gel pens after all, however, colors are bright
