Do people traditionally fish with colored or colorless lines?

Is the landlord a traditional seven-star float or a float? If it is a seven-star drift, it is best to use a colorless and transparent auxiliary line. The thread is soft and does not block the mouth, so it is not easy for fish to find the thread when eating. If it is a float, it is best to use colored lanes for large lines and transparent sub-lines. Generally, colored lines are lanes, which are suitable for main lines, while colorless lines are mostly auxiliary lines, which are suitable for auxiliary lines. The performance of these two kinds of fishing lines is different.
