You can change the color of the end cap of the DULO RC maintenance driver.
The set of three comes in three different colors, so you can use them in a variety of ways, such as color-coding them according to the screwdrivers or sizes you use most often, or unifying them with your favorite colors.
*If the rotation becomes stiff, applying grease or oil will make it rotate more smoothly.
