Use same background color as outlook for a windows form

Question

I hope you can help me with this question because I have no idea even how to look at it on internet.

I'm doing an Outlook Add-In. When you press a button, it displays a windows form I made (very similar to a Message Box but with a textbox on it). I want the color to be the same as in outlook. I noticed Outlook has 3 different set of colors (Silver, black and blue). How can I make so that my form has the same color as outlook?

I think that this link could be useful. Furthermore you could use this to set the background color of your form starting from rgb value.
