What Can Be Learned From the Photographs of the Rare Uncontacted Tribe?

"Rare uncontacted tribe photographed in Amazon" came the title on the first page on Yahoo. The quality of the photos seemed like a lousy cellphone picture job. In one of the photos, the clearest I would assume, two men were poised to fire their arrows, covered in bright red color, and in another, many of the tribe members were covered in either black or red.
I could not but help wonder "how can they make such beautiful colors?!
So, what can we, the Palestinians, learn from this experience?
I would assume that whomever wishes to contact this tribe will walk in shitting their pants.
Literary.
Heavy police and army presence. Major Intelligence agencies will be put to use, all shitting their pants.
And then the fainting journalists. And major media networks finding the story of the century: "Watch it tonight at 11, our OWN convoy travels among the first ever Modern World delegates hoping to negotiate a peace treaty with an uncontacted tribe in the Amazon"
You got the picture.
The "Modern World" will justify this fear by saying that no disruption to the lifestyle of the tribe was hoped for, so highest precautions were taken. Were in reality, the fear of not knowing what your negotiating "partner" is thinking is greater than any of your fears.
Today, and at least for the past 30 something year, since the PLO decided to bow down to the will of the world's community, the Palestinian negotiator has been the town's idiot, or in better terms, the world's community idiot. No one likes him, he keeps getting slapped around, but then sometimes he gets a small reward, a Popsicle, or whatever else no one will eat. No one ever walks towards our negotiation table shitting their pants, and since the Palestinian heritage is found only in memories, no one cares to disrupt or save the Palestinian tribe's lifestyle.

I loved the Red pigment the tribe used. I demand we go ask them how they made it.
You know, just so we can watch my prophecies come to life.
