Do you like pink line for line watching or think that it blends in too much as the day goes on? 

Either I guess, but studies have shown that humans see shades of green better than any other color, so maybe a lime or otherwise bright green would work better here. Thankfully I just feel the bite.

I've tried red (it turned pick) and prefer hi vis yellow by a long shot.

I really like the sufix pink metered line.

Pink is thought to be less visible to fish, chartreuse/bright green more visible on the surface to anglers.

As long as you aren't color blind pink shows up well, but the reality is the vast majority of PE lines will fade, fairly fast with heavy use.  

I like Sunline Sniper BMS. It is multi colored fluorocarbon. It shines bright out of the water and can be easily seen in pretty much any condition.  For braid, I like YGK Upgrade in green. It's easy to see the green and it has a white marking about every 3 feet. 

I have used yellow 65 lb braid for flipping thick cover where the line will not affect bass so much in the heavy shade.   I also use the same line when frogging thick cover and mats for the same reason.  I really like it for frogging and have had great results with hook sets and pulling them out of heavy weeds.  On sunny days I can easily see  that line jump in the thick jungle.

832 yellow over their green.

Yellow for what I want to see it

Sufix 832 Hi-Vis Yellow and Yo-Zuri Superbraid Hi-Vis Yellow are much more visible to me than Smackdown Flash Green - yes, I've tried all three.

I've used yellow braid.  No pink.  Have braid in blue and white.  Yellow is easy to see.  I also am a fan of Siege Neon Tangerine.  Have Big Game in Solar Collector.  Haven't spooled any on a reel yet.  Very bright on the filler spool.  Hopefully it maintains that brightness as a single strand on the water

If your wearing Costa's 580's with copper lens and green tint.  The light greens will pop out the most.  Brightest line I've seen so far are the Sunlines light green lines.  The Costa glasses really help to pop that color.  I've tried most the line that has been posted on here

Bright green for me.

Greetings All,

I realized this bit of marketing information may help to support an opinion on the merits of different colors.

 

Notice the label used as a description for each variation of line color.

 

I hope this helps. Be well, and Cheers!

 

This is what I use. It changes color about every 2 feet so there is always a color that I can see.
