Background code in WPF changes the font or background color

A memo. Once write code to change the background color and then suddenly can't remember, now record down, later standby.

This.lbl.Foreground = new SolidColorBrush (Color.FromArgb (255, 255, 0, 0));
This.lbl.Foreground = new SolidColorBrush (Color) colorconverter.convertfromstring ("#f0f00f");

This.lbl.Foreground = new SolidColorBrush (Color.fromrgb (255,255,255));

The first is to use the ARGB format, and the second is to use hexadecimal format, which is very common in WPF, and is recommended for use. The third is the use of RGB code, RGB to hexadecimal online there are many small programs, conversion is quite convenient.
