I believe pretty much all mantis can move as fast, they just need some heat and sunlight to keep them going, just like reptiles. There are many colours for this species. I had light green, green and dark green, light brown, brown, dark brown, brown with dark brown stripes, pale yellow, green with light brown/orange like pale stripes and finally one, only one with a weird mixture of green and brown. Some parts were green, others light brown while major parts were mixed together. That poor unique female died eggbound a couple of years ago.
A long time ago i believe i had an albino praying-mantis, with an yellowish almost white colour with dark eyes. That one died shortly before adulthood due to my inexperience, cooked by the sun in a poorly ventilated plastic container. I wish i had taken a photo of that awsome white mantis, unfortunately i was way too young. The only thing i can remember of was when caught her and when i found her cooked in the container, with her eyes full of blood....
I got carried away by the colour topic. So, short story even shorter: This species can have as common colours many tones of green or brown. For uncommon colours i consider the yellow or very light brown and the addiction of stripes along the abdomen. The rest is pretty much rare. There might be new colours out there to find out.
