Why the color is so different?

The pictures are from Google. It says that both of them are Blaberus giganteus. But the color is so different, why? Are they the same specie?

The second photo is Archimandrita tesselata. The first photo is Blaberus giganteus. Be careful when you are looking at roaches on google since the picture could be one species, while the species you are looking for is mentioned on the website the photo is from.
