[SOLVED] Change bg color

Hi, i've installed the B&W theme in my Joomla 3,5
Now i would like to change the background similar to my logo.
I've opend the costumiser in the style section and made a copy of one style.
now i changed the color of the background to pink and saved.
still the background is green of the copy of the green style
what have i done wrong or did i forget?

Please set your new created "style" to default in:
>> Template Options > Layouts > Styles

The new created style was set to default already..

The color is set to "green" see image attached.
And your logo is a lil bit to big >> 3400 pixel ???

Still working on the logo for now just set to 100% to see how it works on difrent screens.
I've used the custumiser in the style settings and set it to pink as you can see in my image
should i edit the theme.css by hand than?
