这跟Linux系统有关，CentOS的链接文件默认配色在浅色主题下看起来就很亮，如下图
解决方案：修改CentOS配色：
每次只能改一个用户的配色，要改哪个用户的，就切换到那个用户之后执行以下操作：
1.cp /etc/DIR_COLORS $HOME/.dir_colors
2. vim $HOME/.dir_colors
3. 把文件内容全部清空，复制以下代码粘贴进去保存，然后使用reboot重启即可生效。
# Configuration file for the color ls utility # Synchronized with coreutils 8.5 dircolors # This file goes in the /etc directory, and must be world readable. # You can copy this file to .dir_colors in your $HOME directory to override # the system defaults. # COLOR needs one of these arguments: 'tty' colorizes output to ttys, but not # pipes. 'all' adds color characters to all output. 'none' shuts colorization # off.
