Question

I have a value created by the win32 api function ChooseColor and I want to convert it into a rgb hex tripplet. How do I do this. What exactly is the number returned by ChooseColor?

Answer 1

As you’re doing this in .NET, you can use the COLORREF value and convert to a .NET colour using:

Color colour = ColorTranslator.FromWin32(myColorRef);

If you then want it as an HTML hex triplet string:

string htmlColour = ColorTranslator.ToHTML(colour);
