Open UI - How to Change OOB Tangerine Theme to different color theme?

Hello Friends,

I'm trying to do POC on Siebel Open UI. Siebel OOB provides 2 themes.

       a. Gray

       b. Tangerine

I copied the existing OOB tangerine theme CCS files and renamed to arjun green color theme css. I tried to change to green color in theme-arjun-green.css file and I don't see my changes refelecting.

                          theme-base-arjun.css

  theme-arjun-green.css

  theme-nav-tab-arjun-green.css

  theme-calendar-arjun-green.css

                          theme-nav-accordion-arjun-green.css

I also modified the custom theme.JS file and add the code to look for my new themes and also added the new tab to List of values.
