After a quick subclassing of Windows.Forms.Label and then noticing that the default Label is able to use semi-transparent background colors just fine, I wonder whether there is actually a way to pick them in Visual Studio. The Color picker in the property Grid allows me to pick custom, Web and System colors but doesn’t allow me to define an alpha value.
Right now I’m doing this through code:
this.lblTime.BackColor = Color.FromArgb(96, Color.Black);
but it’d be nice if the Designer itself would allow for that in the first place.
Am I overlooking something or is this actually not possible?
If you know the RGB value you want, then you can just enter, by hand, into the color property field:
128, 255, 255, 0
to get a 50% transparent yellow, or
64, 0, 0, 255
to get a 25% transparent blue…
