We had respond this question via private email. I hope you got that email.
And regarding to the main theme color, we don’t have specific feature to change main color of theme, all the existing option are grouped on color section of customizer, header setting, single post/page setting, homepage section and woo commerce setting
Other than this theme setting,you need to write custom css to change the color on different areas.
If you find bug on our theme then we will update the theme fixing all the bugs as soon as possible. And regarding to main color of theme we will add this featured on near future and will let you know about this.
We have reviewed your support request once more and we will be making an update to the customizer options so you can set the colors of the navigation and widget titles.
This should give you more flexibility to customise the look of the theme.
We aim to have this update out by tomorrow.
We are going to update you via email when this new version is ready for you for download.
