See http://msdn.microsoft.com/en-us/library/system.windows.controls.control.background(v=vs.110).aspx[^]. For numeric colours use a string in the form of "#rgb", using the hex values 0 through F, or 00 through FF for each character position. Thus "#F00" and "#FF0000" both represent the colour red.

There isn't an easy way to get the colour with alpha included from a hex string in this way.

I think your answer depends on where you're getting the colour and alpha values from.

The RGB colour alone can be parsed from an HTML hex string:

Color colour = ColorTranslator.FromHtml("#E7EFF2");

If you have a separate alpha value you can then apply this (docs):

Color colour = ColorTranslator.FromHtml("#E7EFF2");
Color transparent = Color.FromArgb(128, colour);

Alternatively you may need to parse the string and split it out to convert the hex pairs into integer values.

PS excuse English spelling, but colour should definitely have a 'u' in it :)
