Can you explain how to successfully complete the run of 4 phase 10 in the game?

To successfully complete the run of 4 in Phase 10, you need to collect and lay down a sequence of four consecutive cards of the same color. This means you must have cards numbered 1 to 4 or 2 to 5 or 3 to 6, all in the same color. Once you have this sequence, you can lay it down during your turn to complete the run of 4 phase.
