Preset colors can be specified for both handwriting and highlights.

However, the preset of the text box is not changed.

The problems that arise here are:

It is difficult to change the color of only part of the text box
-> It is possible to change some colors through customization, but if you try to change it using a color code, the entire text box is selected and some changes are not made.

If you want to change the color of only some of them, you need to add text boxes, create spaces between sentences, and align the text boxes added in between them.
-> It is difficult to move the text box according to the spacing after inserting a space according to the size of the text box to be changed.
-> In case of adding a text box, when converting to pdf and dragging the content, each text box is converted to a separate text, and the original document and text arrangement are changed.

Therefore, it is much quicker and simpler to change the color by designating a preset that the user wants, and it is also convenient to create a document.
