Instructions for the task:
The name of the color (for example, "black") is displayed on the screen and can be written in the same color (for example, "black") or in a different color (for example, "blue"). If the name of the color and the color of the word are the same (the word "black" is written in black), the user must press the spacebar (or a button on the screen, in the case of using a touch screen), and in the opposite case (the word "black" is written in blue), the user must not perform no action.
