Using the default Emacs font color will make people crazy. However, after you use Emacs theme, you may still feel uncomfortable with the org mode or muse mode color, or too bright or too dark.
At this time, we can easily customize their fonts and background colors in the following ways.
For Emacs org
Available
M-x Customize-group RET org-faces RET
To define the font color and background color of menus at different levels. Of course, the definition of org mode is a bit special. For common text settings, you need to use
M-x Customize-face RET default RET
To set the general font of the full text of Emacs.
For Emacs Muse
Available
M-x Customize-group RET muse-colors RET
To define the font color, font size, and background color of Emacs muse menus.
How to describe your favorite fonts?
What should you do if you see your favorite font and want to set it as your font?
First find the color you like, use
M-x describe-face
To view the corresponding name, and then use
M-x Customize-face RET default RET
To set the relevant color.
Of course, you can also use some tools to get the color name.
