* Cyan is a combination of blue and green light.
* Magenta is a combination of red and blue light.
* When cyan and magenta light mix, they cancel each other out. This is because they share the blue component, and the green and red components combine to create black.
Think of it like this:
* Cyan reflects blue and green light.
* Magenta absorbs blue and green light.
Since magenta absorbs the colors that cyan reflects, no light will be reflected back to your eyes, resulting in the appearance of black.
