Because obviously describing the difference would be hard for people who didn't have a name for the difference in their language, but that's not the same as actually being unable to find the difference. Could they not notice a border between the different colors? Could they not say anything about which was lighter (assuming one was and they had words for "lighter" or "darker)? Were they unable to tell if the color was switched while they weren't looking?
Here's the
video showing the experiment. Basically there's 12 green squares in a circle, but one of them is actually blue, at least according to how we describe colors. But the Himba people use the same word to describe both colors. They don't have to name the color, they just have to point to the one that stands out as different. It takes them longer and they're more prone to errors as compared to Westerners doing the same experiment. However, a little earlier in the video, they did another experiment where all the squares were what we would describe as green, but one of the greens was slightly different. The Himba use a different word for that oddball green and they can spot it instantly. But Westerners have the same trouble here as the Himba had in the other one. So this seems like a case of perception, not simply people describing similar phenomena with different words.

A different
section of that same podcast mentioned that researchers have successfully cured color blindness in monkeys. They injected the genes for the missing red cones into the eye, and over time the monkeys could see red. When asked if this could be used on humans, the researcher said yes, but it awaits evaluations as to what benefit this gives and if it outweighs the inherent risks in a procedure like this. Anyway, I was pretty surprised to hear that we could cure color blindness.

I don't think that's the same as saying language is necessary for thought, and it's also important to note that even if it is true it doesn't support the S-W claim that people who speak one natural human languages are constrained from having the same thoughts as people who speak other languages.
I don't know how accepted the theory is, but the person quoted for the podcast clearly indicated that language is necessary for thought. It's been a while since I listened, but I remember he said that pre-language children don't think, at least not how we normally think about thought. Also, Ildefonso, the man without language (thanks morriswalters!), had trouble describing his life before language. If he merely lacked the words to describe his pre-language life, then this should be fixed with language. But it seems that a lack of language impaired his ability to process and store the events of his life. At least that's what I got from the podcast when I listened last. (Again, it's been a while.)
As for whether any natural human languages impair our thoughts, I am doubtful. It seems reasonable that a language would naturally spread to overcome these constraints since people are so innovative.
A gentle answer turns away wrath, but a harsh word stirs up anger.
