What color do fish like the most?

Fish can’t see many types of colors as humans do and some fish species have better color vision than others. So it is hard to tell a single color that every fish type like. But fish like contrasting colors like red, orange, yellow, white, green, etc.

Many anglers say that green light and white light are great colors to attract fish to boats and docks.
One of my friends have an experience like this, one day he caught a lot of fish on a silver minnow spoon with a small red plastic tab on the split ring. After the red plastic tab was finished he didn’t use another then he realized the fish were attacking the spoon.

Conclusion

While fish perceive color differently from humans, they undeniably possess the ability to see and use colors in their underwater world. Through their unique visual systems, fish have adapted to make the most of their surroundings, ensuring their survival and success in diverse aquatic environments.
