Which of the following represents a negative meaning associated with the color orange?

The option indicating a negative meaning associated with the color orange is closely tied to the concept of caution and the ghost-like connotation. Orange is often used in safety equipment and warning signs, which can evoke feelings of alertness and anxiety in certain contexts. It can signify a need for awareness or action, as seen in traffic cones and safety vests, signaling caution to onlookers.

This contrast with the other options is evident; calmness and serenity, warmth and vibrancy, and peace and safety all represent positive or neutral associations with color. While orange can indeed radiate warmth and vitality, its association with caution and alertness is what underscores its negative connotation in specific situations. Thus, understanding the dual nature of colors and their context is key in floral design and overall aesthetic choice.
