[Star Wars] How did the Jedi blend in on Geonosis before they ignited their lightsabers?

Since the Jedi are different species from the native Geonosians in the stadium, how did they avoid being noticed as they would look out of place?

It's a hybrid variant of Mind Trick and Force Concealment. A Force practicioner can exude an aura of "normalcy" allowing it to be seen as "just another part of the crowd". People will gloss over the Jedi's presence and won't have clear memories of having seen it afterwards, as long as the Jedi doesn't do anything to stand out -- like igniting a lightsaber.

Of course, the Jedi most experienced in this skill are generally diplomats and advisors, those who don't wish to draw attention to themselves. The fact that they were the ones chosen for this assignment, rather than the best front-line combatants in the Order, is a large part of why so many (about 180) died on Geonosis. The Jedi were in large part sent to *investigate* Kenobi's report of the Separatists on Geonosis; they were prepared to defend themselves, but full-out war wasn't quite expected.
