This addon allows you to easily control the color mode random color. 

Unfortunately it happens that the objects next to each other have the same or very close to each other color, which is why the meaning of random color mode is lost. This addon allows you to select by brute force color suitable for you. 

Since the random color technology is tied to the name, the addon adds a prefix, which you can remove at the end of your workflow using a special button. Everything is simple and convenient, especially for you.
