Color as Channel

Color in visual communication is not decoration; it is channel. Each named color in a document — black text, red warning, blue link, orange highlight — carries accumulated semantic weight from centuries of convention. The reader who sees red in a paragraph processes it differently from black before she has consciously registered the word. This is the pre-attentive layer of visual cognition, and it is the layer at which AI-generated imagery most unpredictably intervenes. A language model that produces inline SVG with four distinct colors is not making four aesthetic choices; it is selecting four positions in a shared cultural signaling system, often without understanding what the positions mean. The test of whether this matters is whether the resulting artifact communicates or merely performs communication — the fluency trap extended into the visual domain.
