Is PIXI force us to use PIXI.Application instead PIXI.Renderer ?

[Azern]

I have some trouble that I don't know what happen
I just want to change the background color of my renderer here
 

var webGLRender = new PIXI.Renderer({
antialias:true,
width:300,
height:400,
backgroundColor:0xf0f0fe})

as you see, the color there is not black, it's some grayish. But when I see the page, it's just black. The screen size is correct, only the color that's not working.

I've also tried using option as _backgroundColorRgba  and _backgroundColorString but still not working.

As for backgroundColor - it works in pixijs examples, you should debug whats happenning.
