Hi,
we can’t access to your site because it is under construction, we see only coming soon page.
When you set main color in Customizer, all colors in theme would be change, but there is some places that you can see our original orange color. In this theme you can edit main color, but some colors you will need to set through elements (shortcodes).
So, here are some advice’s. (we change main color on our theme theme to purple and test this)
For button in Revolution slider:
if you want to change button background color on Revolution slider to be just like the main color on all places in site, edit your slider and click to that button. Then go upper to Style blue button. On the left of that button you have arrow. Click on that arrow. Then you see menu opens, and on second tab you can see Background option. There you can set background of that button.
You can see that Process bar is also set to orange color. You need to edit Progress bar element through The Creator visual page builder, there you can set Bar Color option. Same is with Metro Boxes element and Unordered list icons (that is on our About us page for example).
All other colors on your page should be like main color you set. We set you some screenshot for more.
Please let us know if you need anything else :)
Kind regards
