Theme Changed appearance after importing from wordpress.com to .org

I just imported my site from wordpress.com to www.ads-software.com via hostgator. The theme I had been using was Sequential, which was blue…now it is purple and I want the blue back. How do I change the color scheme to blue? Also the primary menu bar is above my logo in the header now instead of below the logo – can this be changed? {Im not a coder}
