Problem changing the color

Hi All.

First of all, I want to thank you, people of ACMETHEMES for made so incredible templates.

I’m having a lot of issues triying to change the colors of the theme.
When I choose a different color in the Layout/Colors page, the preview seems Ok, but when i publish nothing changes. I dont really want to stay in that default orange.

I found a half solution in this forum, to add the CSS Code:

.site-header.fixed {
   background: red !important; 
}

So I change the “red” for a RGB code and it works Ok.

BUT The orange color stills in the slider, also in the display-menu button. How i can change it that color too?. Change the text color would be help too.

Thank you so much and excuse my English.
