If your LED strips are stuck on one color when you change colors, it’s probably because you have been pressing the same color button, which reaches peak value. Try using the reverse button to adjust it higher or lower. If still to no avail, check the contact of your pins and reconnect. Poor pin contact may hinder the strips from lighting up completely. In addition, the remote control may malfunction, and you can replace the battery. Rarely the connector pin may be faulty, and we should therefore install it carefully without too much effort to avoid pin breakage that leads to strip lights malfunction.
