the color of [root@localhost ...]# is still white

All the other color seems working fine the same as the example. But the color of [root@localhost ...]# is still white. How can I fix that, please?

Totally guessing here: that might be caused by a custom color defined in your PS1 environment variable.

To confirm if that's the case, type...

echo $PS1

...and then compare the output with the documentation in https://tldp.org/HOWTO/Bash-Prompt-HOWTO/bash-prompt-escape-sequences.html
