Then wait for the green screen.
What is a good reaction time?
For a visual signal like this one, most people react in roughly 200 to 300 milliseconds. Under 200 ms is very quick, and well-trained gamers and athletes often reach that. On a phone, add a little extra time for the touch screen itself.
Your result changes with how alert you are. Sleep, caffeine, warming up and even the device you use all make a difference. Try it in the morning and again at night, and compare.
Can you improve your reflexes?
Yes, up to a point. Practice makes your response more consistent, and sports, music and action games all train quick reactions. Good sleep matters most: tiredness slows you down more than anything else.
