Like I said in the other post, it needs a tolerance value in your algo to be effective; but great start!

There's no perfect chroma key colors in videos on the web. Those videos requires to have the exact chroma key background with RGB 0,255,0. This is why I added a conditional algorithm to check the variance of green color. This condition should work with most of light green colors. 

if (r >= 0 && g >= 230 && b <= 100)
