This issue is from 2016 with no activity. To implement configurable graph colors, first examine the current settings storage mechanism (likely a config file or database). Then locate the graph generation code (probably in a module related to Telegram message formatting). Investigate if there are any existing color related parameters in the Zabbix API integration. Since there are no comments or linked PRs, the approach should be discussed with maintainers to clarify desired settings format and storage preferences.
