Finally, it is perhaps worth noting that, at least as far as we are aware, no one has offered a structural account of the correspondence between colour and basic taste. The same is not true of the relation between brightness and intensity of taste, which might, presumably, be explained by a common coding of stimulus intensity.

Semantic (or linguistic) correspondences: The third popular account is the semantic (or linguistic) one [ 69] and is based on the observation that we often use the same descriptors for qualitatively different sensory impressions. According to the proponents of this thesis, the common use of the same terms might provide the basis for linking sensations across the senses [ 33]. Footnote 14 It is certainly possible that the semantic/linguistic account may build on the statistical regularities of the environment—so, for example, the reason why people associate sounds having a higher frequency with the word ‘high’ may be because such sounds are, statistically speaking, more likely to come from higher in space (see [ 40]). Affective correspondences: According to the affective mediation account, people may simply want to match pairs of stimuli if they happen to evoke the same feeling or emotion or are known to be associated with the same affective state (e.g. [ 5, 39, 66, 68]). Relevant here is the longstanding literature showing that colours are associated with emotions [ 37, 38, 52]. Similarly, hedonic responses are also associated with/triggered by the presentation of basic tastes [ 3, 44, 47, 59]. Hence, given what is already known, the participants in the studies reported in the “ Crossmodal correspondences between colour and taste words: the empirical evidence” section could, presumably, potentially be matching based on the hedonic value or emotion associated with each individual stimulus. No one has, though, as least not as far as we are aware, proposed an affective mediation account specifically of the crossmodal correspondence between colours and basic tastes. That said, it is worth noting that the affective account has recently gained traction as a plausible explanation for the crossmodal correspondence between colours and both fragrances [ 48] and music [ 39]. Further investigation of the affective mediation account could presumably utilize a version of the clever experimentation introduced recently by Palmer et al. [ 39]. Footnote 16 Does the research that has been reviewed above demonstrate that we can all, in some sense ‘taste colours’? Some researchers and designers have certainly wanted to conclude that the tendency to associate colours with tastes reflects a kind of universal synaesthesia (e.g. [ 45]). Early on, Déjerine [ 10] coined the term chromatic gustation (or la gustation colorée) to describe those individuals who reported experiencing certain colours (concurrents) on tasting specific foods (the inducing stimulus). Footnote 9 However, here, it is important to note that while intriguing, it turns out that such cases of chromatic gustation are, in fact, extremely rare (see [ 6, 15] for case studies, and see [ 9] for a summary of different types of synaesthesia).

Are we all born synaesthetic? Examining the neonatal synaesthesia hypothesis. Neurosc Biobehav Rev. 2013;37:1240–53. Some case studies of chromatic gustation are very striking. For instance, the synaesthete “S”, who was thoroughly tested a little over a century ago by Downey [ 15] experienced very vivid colour concurrents that could last for up to 10 min. Footnote 10 These colour concurrents were localized to the mouth and tended to be stronger when S closed his eyes (see [ 15], p. 528) . Downey carefully controlled stimulus delivery so we can be certain that it really was the tastes (in the gustatory sense) of the stimuli that were the inducer in this case. Footnote 11 Another interesting finding was that while colour concurrents were triggered by pure tastants, they were not elicited by food-related odours. Footnote 12 Parise CV, Knorre K, Ernst MO. Natural auditory scene statistics shapes human spatial hearing. Proc Nat Acad Sci USA. 2014;111:6104–8. The existence of chromatic gustation synaesthesia and, more generally, the unusual experiences reported by representatives of the roughly 4 % of the population who count as synaesthetes have often been used as inspiration in the fields of art and design (e.g. [ 23]). Here, though, we wish to argue that the idiosyncratic nature of the synaesthete’s concurrents (this, in fact, being a defining feature of the condition, at least according to some researchers; see [ 21]) means that it is going to be exceedingly difficult to take the concurrent colours that are experienced by a chromatic gustation synaesthete as a useful source of information when it comes to trying to generate specific expectations of taste based on colour that work with the public at large. That said, it should not come as any surprise if it turns out that certain of the taste inducer-colour concurrent mappings reported in those synaesthetes with chromatic gustation end-up matching, at least in a subset of cases, the taste-colour correspondences reported by non-synaesthetes: S, for instance, reported seeing green on being given a sour taste [ 15]. After all, the combination of 10 colours and 5 basic tastes is not so large that some synaesthetes will not present one of the 6–8 associations found in non-synaesthetes by chance. It would also not be all that surprising if (in fact, one might expect that) the matchings learned by individual synaesthetes are constrained by the highly regular correspondences that are present in every one of us (see [ 14]). Where do crossmodal correspondences between colour and taste come from?

Pleasant Taste & Aroma – This fruit drink is not only prepared with natural ingredients but also has a pleasant aroma and taste. The combination of pineapple and cranberry, together with the right amount of sweetness provided by the hibiscus and stevia, makes it a delicious fruit drink. The structural account: According to this account, certain correspondences may have a structural origin, meaning that they reflect the inherent structural, wiring, or processing constraints of the human brain (that is, they are not learnt). One example of such a structural correspondence might, for example, be the mapping of more intense stimuli across sensory modalities, given the similar way in which stimulus intensity is coded across the senses (namely as an increase in neural firing; see [ 54, 60]).

Infants’ sensitivity to arbitrary pairings of color and taste. Infant Behav Dev. 1988;11:245–50. In 2008, Tomasik-Krótki and Strojny had their participants (a convenience sample of more than 500 individuals from 17 different countries, covering a number of continents) via questionnaire: “how they link the colours, red, orange, yellow, green, blue, and violet to the tastes bitter, sweet, umami, sour and salty” ([ 65], p. 253). The wording of the article itself is a little ambiguous as to what exactly the participants had to do. Footnote 4 That said, crossmodal associations between red and orange with sweet, yellow and green with sour, blue with salty, and violet with bitter and umami were documented (see Table 2). A subset of the participants in this study also associated a bitter taste with the colour green. The researchers’ interest in carrying out this study was different again from that in the other previous studies reported in this section. Tomasik-Krótki and Strojny were specifically interested in trying to establish any crossmodal associations between colours and both tastes and odours on the other. These researchers created units of taste (mnians) and odour (fooys) and a permutation system that would allow for the standardized translation of one sensory impression into another across the senses. Is this, the use of crossmodal correspondences to guide the presentation of a dish, anything more than a fad one might ask? Well, only time will tell. But already we have seen another chef Xavier Gomez, from Porto Allegre in Brazil, serving a version of this dish to the diners at a couple of dining events that were held recently (see http://xavier260.com/).
