How to add Color in Designer class in c# .

Hi All,
In C# control property I am able to find only limited colors, there are custom colors but I was able to use only those which are already there. 
Now as per my requirement I want to add color of my choice to my control.
We can use #FFFF using # and alphabet , So there should be other way too.
For me below code works perfect : 

this.BackColor = Color.FromArgb(255, 232, 232);

 

if you go to Color Picker you can see that after color code which start with # there is numbers also .
