Praying mantis's are so cool. Almost all of them can change colors to some degree. What you have, I think, is Pseudocreobotra wahlbergii
Pseudocreobotra wahlbergii. Your photograph is breath taking! If I were you, I'd submit it to whatsthatbug.com to make sure I've id'ed it correctly and so they can put it on their site (if you don't mind sharing). It's one the best pics I've seen!! Fantastic, thanks so much for sharing it!!
Forgot to mention, the link takes you to a page and what I think is your bug is towards the bottom.
