It’s automatic these days. In the past you needed colorlog[windows]
See https://pypi.org/project/colorlog/ search windows/colorama

Description:
Retry of #20272
Current behaviour always installs a script's requirement
This checks if a requirement's project name is available (by import) before it forces installThere is full (including version) requirement handling available inrequirements.py, but this requires a full hass instance and seems like an overkill for scriptsRelated issue (if applicable): fixes #18651
