If you look up this mouse you can get more information. This mouse is called HEMZONE the company is GameStart. This mouse lights up and I want to know how to change the color and if it is possible?
This usually requires a proprietary driver that is usually only designed for Windows or Mac OS X. If you have a PC with those operating systems I suggest you do it there & then maybe the mouse will remember those preferences when you reconnect it back to the Chromebook.
Amazon page for similar product of another brand has a user advising his was HEMZONE. Another user said to change colors on mouse you use a combination of buttons: press forward/back button + dpi toggle between auto color change and just red
This website indicates (under FAQ) that you cannot change the color of this particular mouse. This is echoed by some amazon users as well.
