Creating transparent background in WPF

Question

I have a button with a backgroun image of color white. My button is sitting on the toolbar which has a bacground color of Blue. When the button is sitting on the toolbar, the button looks white, however I want it to look like blue as the the background color of toolbar is Blue.

How should I achieve this in WPF.. Please let me know.

Answer 1

Are you sure you want to use an image? If the image is just a solid color, you're probably better off just setting the button's background to white and adjusting its opacity. Like:

<Button Background="White" Opacity="0.5" />

Where Opacity can be any value between 0 and 1.

EDIT: I'm not sure what you mean by "shades." Are you aware that you can set the background of a Button to a gradient? You'll want to change the colors I'm sure, but it will look something like this:

<Button>
    <Button.Background>
        <LinearGradientBrush>
            <GradientStop Color="Yellow" Offset="0.0" />
            <GradientStop Color="Orange" Offset="0.5" />
            <GradientStop Color="Red" Offset="1.0" />
         </LinearGradientBrush>
    <Button.Background>
</Button>
