Description: The label color in data visualization refers to the color of the text used to identify different elements in a plot. This aspect is crucial for the clarity and readability of visualizations, as good contrast between the label color and the plot background can facilitate the understanding of the presented data. In various visualization libraries, label colors can be customized using color names, hexadecimal codes, or RGB values, allowing users to tailor the appearance of their plots to specific needs or desired aesthetics. The choice of color not only affects the aesthetics of the plot but can also influence the perception of information, as certain colors may evoke different emotions or associations. Therefore, label color is a fundamental element in the design of effective and appealing plots, contributing to the visual communication of data efficiently.
