Final answer:
The most important thing for a visual text to do in order to convey meaning is to effectively communicate a message or concept.
Step-by-step explanation:
In order for a visual text to convey meaning, the most important thing it needs to do is effectively communicate a message or concept. While colors and symbols can enhance the meaning of a visual text, the main goal is to clearly convey a message to the audience.
Being abstract and open to interpretation may create different interpretations, but it does not guarantee effective communication of a message. Similarly, including complex symbolism that confuses the audience may hinder the understanding of the intended meaning.
