What might be a consequence of incorrect color representation in event materials?

Misleading expectations is a significant consequence of incorrect color representation in event materials because colors evoke specific emotions and associations. For instance, if an event is promoted using a vibrant color scheme that suggests a lively and energetic atmosphere, but the actual event materials feature muted or dull colors, attendees may feel disappointed or confused upon arrival. This mismatch can impact attendees’ perceptions of the event's quality and the overall experience, potentially leading to dissatisfaction. Consistency between promotional materials and the actual event is crucial for meeting audience expectations and creating a cohesive brand image.

The other options, while they may have valid points in other contexts, do not directly relate to the immediate impact of color misrepresentation on attendee perception and expectation. Event location issues, increased costs, and logistical challenges pertain more to operational aspects rather than the emotional and aesthetic alignment that color representation directly influences.
