Set background color based on the value of a data attribute

Question

I have 16 different section-tags. Every section-tag has a data- attribute to set a specific background-color for each section:

<section data-color="#A3D1B5">

Now I want to set this color as the background.

What I've already tried:
In CSS values using HTML5 data attribute, the answer says it should be possible to set the color like background: attr(data-color);, but this won't work for me.

I took a look at jQuery data() but I don't know how to set the background for all of the section-tags.

Are there any other solutions to handle this with jQuery's .data()?

DEMO

$("section").css('background', function () { //or for code's consistency, i'd use background-color instead
    return $(this).data('color')
});
