Usually they use different shades of one color to make their drawing’s features look artistic and realistic
I’m a little confused by what you mean but here’s my best answer
-table of contents: helps readers know where to look for certain chapters and such. (Organizes book)
-heading: tells reader what a chapter is about
-caption: description of something
-glossary: helps readers know certain vocabulary
-bold faced words: attracts the readers eye
-label: helps to identify something or someone
-photograph: can help a reader better understand a text
-diagram: informative and helps readers know more and understand better
I hope this helps!!
