I’am using 7.9.2 Suitecrm, i need to change task status color on dashlet, but can not find the html code of this. And need to know how to find path of any module.
You need to create a custom dashlet. Have a look at modules/Tasks/Dashlets/MyTasksDashlet/MyTasksDashlet.php. If you set the $this->displayTpl in the constructor, you could create a custom smarty template which styles the status file. You copy the template from include/Dashlets/DashletGenericDisplay.tpl and the customise it.
