I have a Kinetic JS stage and a layer

var stage = new Kinetic.Stage({
    container: 'container',
    width    : STAGE_WIDTH,
    height   : STAGE_HEIGHT
});

var layer = new Kinetic.Layer();

I've set the page color to be #bbb.

body {
        background: #bbb;
    }

I'd like to set the canvas color to be white. But I can't seem to find a method or a way to add a background color to the stage itself or the layer that I add all the object on.

You can also set the background color of your container element through CSS. That's essentially the same as setting the background color of the stage. If you want a background at the layer level, you'll need to add a filled rectangle or similar, as previously mentioned.

I had the same problem, I wanted to add a "background". I added a rectagle with the 100% height and width, with this code:

var rect = new Kinetic.Rect({
            x: 0,
            y: 0,
            width: stageDimensions.width, //full width
            height: stageDimensions.height, //full height
            fill: 'white', //background color
        });
layer.add(rect);

Since I wanted to be able to remove the "background", this is how I manage to solve my problem.

Hope it helps you.

You can change the background color with JavaScript...

document.getElementById('container').style.background = '#fff';

There isn't an API method to add a background color.

Instead add a colored rectangle that covers the layer.

Of course, add the background rectangle before all other shapes.

Old question, but you can use the get properties of the stage, and fill a full rectangle, adding it to the layer before anything else. Sample code:

var stage = new Kinetic.Stage({
  container: 'canvas-container',
  width: 900,
  height: 450
});

// create background
var stageBg = new Kinetic.Rect({
  x: 0,
  y: 0,
  width: stage.getWidth(),
  height: stage.getHeight(),
  fill: "rgb(40,40,40)"
});

layer.add(stageBg);
stage.add(layer);
