Touch-to-Color Cross-Modal Associations Are there Systematic Effects?

We replicate and extend findings on tactile-to-color cross-modal associations. We used nano-engineered material constructions, facilitating future cross-study comparisons on how tactile properties affect visual (color) associations. We obtained systematic associations in normal population, between tactile surface (e.g. rough, soft, sticky) and color properties (e.g., color categories). While gradual color properties (e.g. brightness) also related to tactile properties, these findings were less robust.
