Color of a line should be chosen according to a water color and clarity. Some colors, like green, are usable in many situations, while other colors suit some specific situations.

I will explain more about what color fishing line is best, and answer a few common questions, in the following chapters:

What Color Fishing Line Should I Use?

So, what is the best color of the fishing line?

Unfortunately, there is no simple answer, and every serious angler will have multiple fishing lines to choose from.

So, let’s start with the common colors and their uses:

Yellow/Murky water [BEST for Darker Conditions]

Water clarity dictates the line color. Bright colored lines like yellow have a few applications.

Anglers can see it well and observe it in darker conditions. This could be beneficial for inexperienced anglers who rely more on their sight, instead of how the line feels.

In murky / dirty water, yellow won’t be that visible to fish. Unfortunately, this color is not the best one for clear water and even in murky waters, suspicious fish may avoid it. Luckily, hungry predators will focus on the lure and ignore your line.

Green/Various conditions [BEST for Freshwater]

If you are looking for a color that can be used in numerous situations, green is the way to go. Among all line color choices this can be described as all-around.

This color will blend in many surroundings, even outside of the water, for extra suspicious fish like carp, which can see you on the riverbank.

Green is best color fishing line for freshwater. Freshwater usually has some green tint, as well as the surroundings. In extremely clear water, and clear saltwater, green will be visible and, in those conditions, think about other options.

Transparent/Clear conditions [BEST for Clear Water]

Transparent is very good color for saltwater fishing, or extremely clear freshwater.

These work well in many conditions, but they are the best when the water is transparent too. They reflect light in almost the same way as water does and they will blend in perfectly. This option works great for careful and suspicious fish in ultra-clear water.

Blue/Saltwater [BEST for Saltwater]

Light blue is the best color fishing line for saltwater because the color is similar to saltwater color. When the water is not completely transparent, blue line is the best choice. Of course, you can always play with different colors and see what works the best.

Many anglers ask what color of fishing line should I use for certain fish species? Here is the answer but keep in mind that you should consider other factors too.

Red [Good for Deep Water]

Red fishing line is best used in low light conditions or when fishing in clear water. The red color of the line provides better visibility and allows the angler to better see their line against the water.

Some line manufacturers also claim that red line is less visible to fish, especially in deeper water where the color changes to a more natural hue. This can be particularly advantageous for anglers targeting spooky or finicky fish species. And as I said - these color is the first one to disappear.

How Does Water Depth Impact the Line Color Visibility? [+ CHART]

The visibility of fishing line color is impacted by water depth.

Generally, the deeper the water, the less visible the line color becomes (really deep becomes invisible). This can be attributed to the way light and color are absorbed and dispersed in water.

A chart depicting the relationship between water depth and line color visibility can help anglers choose the most appropriate line color for their fishing conditions.

Understanding this relationship can improve fishing success by ensuring that the line remains as inconspicuous as possible to the fish.

What is the Least Visible Type of Fishing Line?

Fish can see the fishing line. So, the color and type of fishing line really matters.

You have to consider how a certain color and types looks under water column, not on the ground. So, let’s start with almost invisible line type, the fluorocarbon.


Fluorocarbon line, especially in clear water, is almost invisible. It has light reflection properties very similar to water light reflection properties. This type is excellent for fish that are easily scared and suspicious.

You can find red/pink fluorocarbon on the market and it can seem crazy, but with water depth, as certain wavelengths of the sunlight can’t reach very deep, these colors are the first one to disappear. For fishing in deep waters, this is a good option.


Monofilament lines are a bit more visible than fluorocarbon, and available in different color options.

You will usually see mono lines in yellow, red, blue or green color, or even a transparent option. All these colors appear differently at various depths and colors of the water.

Braided lines

Braid lindes have some excellent properties, but being invisible is not one of them. If fishing with braided lines, you will have to pay attention to the color and choose a suitable one for a given situation.

FAQs about Fishing Line Color:

In case you still have some questions or doubts, I will answer some of the important questions regarding fishing line color.

How Does Fishing Line Color Impact Fishing Success?

As already mentioned, fish can see under water. Every living creature, including fish, has an instinct not to go towards danger or suspicious things. If the line is highly visible, no matter how tasty the bait or hungry the fish, that fish will avoid it.

If you are using highly visible colors in crystal clear waters for example, the fish will see it from a great distance and will feel threatened.

In murky waters, line is naturally less visible, so bright colors here can actually benefit the angler who is observing them. Seeing your line can increase your fishing success.

But not all fish react the same. Some see better and are more cautious by nature, while other fish, like catfish, rely on smell more than sight. So, wrongly, or even correctly chosen line in regard to fishing conditions does not impact all fish equally.

Does the Color of the Fishing Line Matter When Fishing During Different Times of the Day?

Time of day is related to light conditions. If there is bright sun at noon, visibility under water will be highest. Around dusk, dawn, or even night, there will be much less natural light, so everything, including lines, will be less visible.

This greatly affects how the line is visible at greater depths. When the sun is shining and it is positioned high on the sky, it will illuminate deeper parts of the water column and make your line visible at greater depths. As the sun is going down, this visibility at depths will drop and only the parts near surface will be more visible.

As already mentioned, with depth some colors fade and disappear, and during day those depths are higher than during dusk or dawn.

The same goes for cloudy days. So, when choosing line color in accordance with time of day, pay special attention to midday on sunny days and choose less visible options. At night, you can get away with more visible lines.

What Color Fishing Line is Best for Fishing Over Rocky or Gravel Bottom Structures?

Rock and gravel can be a great place to position your bait for numerous species. Rocky structures are excellent hiding places and hunting grounds for various species.

Most often, rocky structures are grey or brown in color. You want your line to create as low contrast as possible. If the water is clear and the bottom has grey rocks, you most definitely won`t lay a fluorescent orange line over it.

What you want to accomplish here is to create natural shades. That is done by using the line that resembles rock or watercolor, or even the completely transparent one.

In blue waters and light-colored rocks go for blue, grey, or white. In green waters and brownish rocks, go for green, brown, or even shades of yellow.

Should I Use a Specific Fishing Line Color for Fishing around Docks, Fallen Trees, or Other Cover Types?

When it comes to fishing around obstacles, go for colors that blend in the habitat, as already described in the previous chapters.

As docks, trees, and other structures vary in color, if you want a “one color for all” my advice would be to go for green lines in freshwater as they go well in numerous conditions, water clarities, and daytimes.

However, there is one other thing to consider here. Obstacles can cause line snagging and even breaking. Here you will need lines with high abrasion resistance and a bit stronger one.

Don't worry about visibility a lot as the structures will hide it. Use leaders for lower visibility but go for stronger main line.

If you have been wondering what color fishing line should I use, now you got the answer. Keep in mind that the water color and light are the most important factors when choosing colors of fishing lines.

Except for color, consider the line features as well, because not every fishing line is suitable for a given situation.

And remember, fishing lines have an “expiration date”. Depending on how often you use them or how long they have been sitting in a storage, their properties will change and the line won’t be good for fishing.
