How to set colors for figures in MATLAB?

In Matlab, there are several ways to set the color of a plot:

1. RGB values can be utilized to specify colors, where R represents red, G represents green, and B represents blue. Colors can be set in the form of [R,G,B] with real numbers ranging from 0 to 1. For example, using plot(x, y, ‘Color’, [0.5, 0.5, 0.5]) will set the color of the lines to gray.
2. Utilize predefined colors: Matlab includes some predefined color names that can be directly used to set colors. For example, using ‘Color’, ‘red’ will set the color of the line to red when plotting(x, y).
3. Instead of using decimal values, colors can also be specified using hexadecimal values. The format ‘#RRGGBB’ can be used to set colors, with RR representing the hexadecimal value for red, GG for green, and BB for blue. For example, plot(x, y, ‘Color’, ‘#FF0000’) sets the color of the line to red.
4. Using color mapping: Matlab also offers some predefined color maps, which can be used to set colors for different elements in the graph by specifying the name of the mapping. For example, you can use colormap(‘jet’) to set the color map of the current graph to rainbow colors.

It is important to note that different drawing functions may have varying levels of support for color parameters, you can refer to the documentation of the specific functions for more information.
