That leads to the extremely common confusion of if "disable flash" is a description of what you will do when you interact with the control (the verb describes the action to be done), or a description of the current state (it's a "yes, disable flash" confirmation). Both are common. Some apps even use both on different controls.

Compare that to a checkbox next to "Flash is disabled". Or a toggle. Or a button. The control and its vague state or bad color blindness choices doesn't even matter if you're clear with your words.
