A newbie might think can fish see fishing line and that’s why choosing the perfect color for the fishing lines can be very confusing. Even if you forget choosing the best fishing baits, or selecting some fancy fishing rods, the headache of choosing the perfect color of the fishing line is insane.

Don’t get confused while you’re at a shop, let’s learn something about the colors of fishing line. And also now if the fish see the lines. Hopefully reading this resource will help you to choose the right fishing line color in an easier way and your headache might be removed.

Consider several things before putting new lines on your fishing reel. Some common questions might appear in your mind before putting the line. Some of them like- What type of line is better for fishing? Should I buy a line with no stretch or some stretch? Then you may think of the type. Monofilament, braid, or fluorocarbon?  After choosing the type, you may think of the color of the line. Is it good to go with an invisible line or a colorful one? Is it okay to have any fishing line or the fish can see the line?

Before knowing if a fish can see or not, know what an angler can see. We’ve done a survey with a bunch of professional anglers. Based on their and professional experiences and manufacturer claims we’ve got a very good understanding of exactly when and where you should use them.

We’ve described the three major types of fishing lines with their benefits and usage.


Fluorocarbon line the most invisible fishing line on the market. This line is designed to refract light as the water does, which makes the line as much invisible as it can. Anglers can have huge advantages with the fluorocarbon line like the invisibility feature for all kinds of water clarities. It doesn’t matter if the water is low-height or so clear. The fluorocarbon line has the ability to be near-invisibility as well as deepwater invisibility. Using this line results increased bites from those fishes who scares of colorful lines.


  • More abrasion resistant
  • Less visible to fish
  • Good sensitivity
  • Powerful hook setting


  • More expensive than most monofilament
  • Fast sink rate

Pink Fluorocarbon

Pink fluorocarbon line is made up of such a blend of color which can hardly be detected underwater. You may not believe this easily as it is visible to you. But the manufacturers of pink fluorocarbon lines claim that this line is really hard to detect underwater. And very fortunate, the claim is so true with the pink lines. Our case study from science about this line shows that pink color loses its color at different depth of water.
And it works as expected to catch those color frightened fishes.

Monofilament is the most popular fishing line with several color options to choose from. They are so popular as it’s easy to see this line for the anglers above the water but really hard to see underwater for the fish.


  • Affordable
  • Slow sink rate
  • Good shock absorption


  • Less abrasion resistant
  • Less sensitive
  • Higher visibility compared to fluorocarbon


Most probably the most eye-catchy color in this universe is Yellow. This bright color is really easy to see from above for the anglers. You can also notice the slight bites by using these lines. Fish can easily notice the color of the line and might skip eating the lure. Unlike the clear water, for dirty water, this line is a very good choice.


Red color lines are mysterious. They become invisible underwater but in a different manner. Usually red objects lose their color underwater and turn black. It helps the anglers to spot their line above water easily and fools the fish by changing the color.

But most of the red hook producers claim that red hooks get more bites than any other colors as they are visible underwater. Actually, red hooks are made of some metal finish and that’s why they are visible and attract the fish.


A gentle color that blends with water very well. You might notice that a huge number of anglers have some green tint fishing lines. Because the green line blends with water and its surroundings. In the case of clear water, the green line can’t be a good choice. But you should have one as it can blend with almost all kind of environment.


Clear monofilament can be your best choice if you’re concerned about the witty fish. Those fish are aware or scared of colorful lines and that’s why clean be can be your best choice. It also works with all types of water and the environment. We prefer the clear blue one which is more visible to see above water.

Braided Lines

If you are concerned about the color of fishing lines, this one is perfect for you. Except for this one, the braided lines have so many advantages. Thin line with better strength, extremely cast capable and non-stretchy are the features that made this line so popular and best choice. They are so good for heavy-duty and for almost any kind of water, especially the muddy water.


  • High strength
  • Smaller diameter
  • Powerful hook sets
  • Excellent sensitivity


  • More visible than fluorocarbon
  • Expensive
  • More challenging to knot securely

Time To Finalize The Decision!

An angler should never give too much credit to the fish. Braided lines were so popular until the introduction of monofilament. They are still popular but some of the anglers blame the color of the line. That’s all about an angler’s personal conception. If you think the fish would see the line and not bite their bait, definitely it’s your own opinion. Many of them also use brighter lines for personal reasons.

Most bass anglers’ favorite pick will be a plastic worm to have some bigger catches. In nature nightcrawlers only come in one color.  In the market, we have a wide variety of several bright colors. Some of them don’t look natural at all.  But the bass loves to have those colorful worms.

So now, how important is the line color and why?  In terms of your confidence, line color is very important. Most of the best anglers will say that bright color is not an issue of fishing. Professionals want to see their lines above water for striking, they don’t care about invisible lines. It helps to strike very well when you have to use any slower-moving baits or jigs.

Clear Fishing Line

Clear is the very basic fishing line in the market. If you’re not a regular angler, a basic clear monofilament fishing line can be a good choice for you. The best choice in terms of clear fishing line which is invisible underwater is Fluorocarbon fishing lines. 

Yellow Fishing Line

Spotting fishing lines are so popular among a huge portion of the anglers. They like the yellow fishing line or a bright neon green fishing line as the lines are highly visible. As it is so visible for you, it is visible for the fish also. We recommend using these fishing lines in muddy water. We also recommend using it for a bobber.

Green Fishing Line

 More often water has a green tint by its nature.  If you have a fishing area with green like water, green-tinted fishing lines are highly recommended for you. We don’t recommend using a green-tinted fishing line if the water is very clear.

Blue Fishing Line

Sometimes you might go fishing in an area with a lot of blue water. In that case, we recommend using a blue-tinted fishing line. Be careful while seeing the color of the water because the water tends to be green more than blue. In that case, we recommend a green-tinted fishing line over the blue one. 

Red Fishing Line

Red fishing lines turn black underwater, said by most of the water divers. Fish can rarely detect a red line and you can have some good catches. But still it is not a fact, it’s a debate.

Final Thoughts

Choosing the perfect fishing line by considering the colors and strength is really confusing. In terms of fishing, there’s nothing certain but still, you can apply the best technic to catch better. We recommend buying several color lines in several situations and places. As of science, a multi-colored line blends very well into the environmental background of water and it’s harder for a fish to see and detect the line.
