From doing a lot of searching though, there's a could possibility that those chairs were spray painted. There seems to be much more vibrant colors in spray paint.
Take that 'exact' picture to a reputable paint store. I think they can actually use a scanner and input it to their computer for an 'exact' match. Make sure you use a white primer on your wall first, to get the true color. I love that color. Good Luck!
Go to a local paint/hardware store and they will mix it up for you. Make sure before you pay they show you a DRY sample of the mix.
