Categories can affect our perception of the world, rendering between‐category differences more salient than within‐category ones. Across many studies, such categorical perception ( CP ) has been observed for the basic‐level categories of one's native language. Other research points to categorical distinctions beyond the basic level, but it does not demonstrate CP for such distinctions. Here we provide such a demonstration. Specifically, we show CP in English speakers for the non‐basic distinction between “warm” and “cool” colors, claimed to represent the earliest stage of color lexicon evolution. Notably, the advantage for discriminating colors that straddle the warm–cool boundary was restricted to the right visual field—the same behavioral signature previously observed for basic‐level categories. This pattern held in a replication experiment with increased power. Our findings show that categorical distinctions beyond the basic‐level repertoire of one's native language are psychologically salient and may be spontaneously accessed during normal perceptual processing.
