You can pick between the main 5 "colors" - primary, success, danger, info, and warning. Their actual color changes depending on the toyhouse site theme you're using (found in settings). The template is currently using warning, so you'd need to find the word "warning" scattered all over the html and change the word to one of the others ones. Or, you can use the custom colors version of this template (https://toyhou.se/3079369.charahub-profile/3079374.custom-colors) and you can change it to any color you want by changing the hex number (looks like #123ABC)
