The hypothesis as a whole is not thoroughly discredited; color is an extremely specific case: "The main strand of domain centered research has been the research on color terminology, although this domain according to Lucy and admitted by color terminology researchers such as Paul Kay, is not optimal for studying linguistic relativity, because color perception, unlike other semantic domains, is known to be hard wired into the neural system and as such subject to more universal restrictions than other semantic domains."[1]

That statement by Wittgenstein is far from being the same thing as the Sapir-Whorf hypothesis. For one thing, if you can discriminate colors then you can name the colors, if you want. That is, the limits of your language include being able to talk about those colors, assuming you can discriminate between them. In any case, it's jumping to probably mistaken conclusion to interpret "limits" of language and "limits" of the world that Wittgenstein was talking about as being about same thing as Sapir-Whorf hypothesis concerns.

I think you have a good point, but it is worth noting that being unable to communicate effectively significantly reduces your ability to change the world around you in a meaningful way. If you only have a few words for colors, then you're going to have a hard time exercising fine control over color-based problems.

However, one should also remember that language isn't just words. You can refer to colors by motion (pointing at a chart) or by proxy (using a code like #34F278). So we are limited by our language, but our language is not so limited as to make us fools for not having a word or two.

> [...]psychophysics shows that your ability to discriminate colors does not depend on the words you use for them.

I thought that some of the work on the Himba tribe's perception of colour was, tentatively, showing just that. Their lack of linguistic distinction between green and blue could explain that, in experiments, they took longer to differentiate between shades of blue and green than an English speaker would. It doesn't mean they don't see it though, just that it's a more complex task for them.
