Synesthetic metaphors for sensory experiences are the norm, even among sight and sound.<p>Colors are usually described as &quot;loud&quot;, &quot;quiet&quot;, &quot;cool&quot;, &quot;warm&quot;, &quot;hot&quot;, &quot;soft&quot;.<p>This morning I read an album review that described the music as -- “radiant”, &quot;textured&quot;, with a &quot;shimmering glow&quot;, &quot;a gilded set of songs&quot;, &quot;seemingly to soar in a striking display of absolute iridescence&quot;.<p>That sort of language just helps us triangulate an aesthetic experience using the language of our other senses, it doesn&#x27;t mean a sense is any less direct.
