Hello,
To change the footer color go to Theme Options > Styling > Footer > change the color of the background.
Also, you can use custom css to change the background color of one column.
You can create custom footer using Static Block and VC https://www.8theme.com/documentation/xstore/support/static-blocks/ After that in Theme Options > Footer > choose 1 column and go to Appearance > Widgets > add 8theme Static Block widget into footer widget area.
Regards
