What effect does garishness typically have on the viewer?

Garishness is characterized by overly bright, flashy, or clashing colors and designs, often to the point of being tasteless or visually jarring. This overstimulation can lead to a feeling of being overwhelmed, as the eye and brain struggle to process the chaotic imagery. As such, when something is described as garish, it tends to assault the senses, making the experience of engaging with it less enjoyable and more difficult to assimilate. This understanding aligns with the notion that garishness has the effect of overwhelming the senses, making that the most fitting choice.
