In recent years, many philosophers and scientists have argued or accepted that it is impossible to learn primitive sensory concepts like "blue" and "red". This paper defends a more qualified picture. I try to show that some received characterisations of "learning" are nonequivalent and point towards different learning-nonlearning distinctions. And, on some ways of specifying such a distinction, it might be correct that we do not and cannot "learn" a concept of blue. But on other ways of specifying such a distinction, we can and do sometimes "learn" a concept of blue from experiences of blue. The latter part of the argument connects with some traditional "abstractionist" views, and I defend the present claims in view of some widely circulated concerns about "abstracting" concepts from experience. I close with some reflections on how one might, in view of all this, think about "the learning-nonlearning distinction".
