Preset Theme Color Change

See attached preset color in OT Keila Joomla Theme. I want to change it, where to locate this color in CSS files?

And what is color code already given?

Hi,
With this template we only have one color scheme like package

but at least tell us where this color is given in css file?

Hi,
Color scheme is defined in templates/{template-name}/templateDetails.xml
and in templates/{template-name}/assets/css/preset-1.css
