Color.FromArgb will give you what you need. just provide alpha, red, green, blue values.
#FF0000 = new SolidColorBrush(Color.FromArgb(255, 255, 0, 0))
#F2F2F2 = new SolidColorBrush(Color.FromArgb(255, 242, 242, 242))

you just need to convert from your hex string to the appropriate byte values. create a helper function if you want...
private Color hexToColor(string hexString) { hexString = hexString.Replace("#", ""); Byte a = 255; Byte r = Convert.ToByte(hexString.Substring(0, 2), 16); Byte g = Convert.ToByte(hexString.Substring(2, 2), 16); Byte b = Convert.ToByte(hexString.Substring(4, 2), 16); return Color.FromArgb(a, r, g, b); }
