Final answer:
True, color choices should be influenced by color theory and be tailored to the audience's demographic and cultural background to achieve the intended emotional response and message.
Step-by-step explanation:
True. Color selections should indeed be based on color theory and consider the age, class, culture, gender, and trends of the target audience. This is because different colors can evoke various emotional responses, and these responses can be influenced by cultural connotations and individual experiences. For example, while some colors like blue might be soothing in general, they might have different meanings in different cultures or to different age groups. Artists and designers use color theory, which categorizes colors into primary, secondary, and tertiary hues, to create harmony and contrast in their work. Moreover, knowing the target audience aids in selecting appropriate colors that can enhance the intended message or feeling of an artwork or design. In this case, color selections for a piece like a poster would take into account general preferences, such as an aversion to bright garish colors and a preference for soft muted tones.
