CSS3 ::selection behaves differently in FF & Chrome

I'm experimenting with the ::selection pseudo-element in CSS3. In Firefox it works and looks great. My site has a dark navy blue background.

I set the selection so that it looks like this in FF.

But in chrome the same test looks like this. It seems that chrome interprets the selection as semi transparent the resultant color is nasty.

Does anyone know if it's possible to get chrome to behave the same as Firefox.

For reference here is my css:

p::-moz-selection { background:#FFFF7D; color:#032764; }
p::-webkit-selection { background:#FFFF7D; color:#032764; }
p::selection { background:#FFFF7D; color:#032开发者_开发技巧764; }

Thanks

For some reason Chrome forces it to be semi-transparent. However, you can get around this by setting the background using rgba. I have set the alpha value to be just 0.01 less than 1. Live example: http://jsfiddle.net/tw16/m8End/

p::-moz-selection {
    background:rgba(255, 255, 125, 0.99);
    color:#032764;
}
p::-webkit-selection {
    background:rgba(255, 255, 125, 0.99);
    color:#032764;
}
p::selection {
    background:rgba(255, 255, 125, 0.99);
    color:#032764;
}

As Steven Lu has pointed out in a comment to tw16's answer, the opacity treshold is 255/256.

In other words, 0.996 will work but 0.997 will not.

Let's see it in action:

::selection
{
  background: rgba(255, 127, 0, 0.996);
  color: white;
}

::-moz-selection
{
  background: #F80;
  color: white;
}

As you may see in Chrome, this obscures the images. To fix that, we need to apply specific styles to image selection, with a lower opacity:

::selection
{
  background: rgba(255, 127, 0, 0.996);
  color: white;
}

::-moz-selection
{
  background: #F80;
  color: white;
}

img::selection
{
  background: rgba(255, 127, 0, 0.8);
  color: white;
}

In Firefox, there is no way to override the blue selection color on images, it seems.
