Question about theme options -> basic main colour

Hi guys,

I’m trying to change the colours for the main-sidebar. To elaborate, the current main colour under theme options->Basic is colour code: #87c1c6 and turns most of my widgets with this colour. Please see my website: http://www.wakeupv.com. Now i do not want it to be this colour for all page and when i try to change the colour in style.css, apparently the main colour supersedes the changes from style.css. For example, if you refer to my website you are able to see the sidebar on the right hand side, such as: “Trending, Follow Wakeupv, etc” and i try to change their sidebar colour, it won’t let me because of the main colour set in theme options.

Is there a way to have this colour changed? Can someone please help?
Please let me know if you are in need of further explanation
