Answer 1

You are referencing the Color type in the iTextSharp.text namespace. Try specifying the namespace explicitly:

btn.ForeColor = System.Drawing.Color.Red;

Answer 2

You can use the Button.BackColor property

Example :

btn.BackColor = Color.Green;

Correction : OP's question title is misleading and the above is based on that So the answer for the explanation in body of the question will be same as what OP have given

btn.ForeColor = Color.Red; //don't see the reason why this should not work

Answer 3

To change the BackColor use:

Button1.BackColor = Color.Red;

To change the ForeColor use:

Button1.ForeColor = Color.Red;

You can use both of them for the MouseMove event.

To reset both of them use the MouseLeave event with this code:

Buttton1.BackColor = SystemColors.ButtonFace;
Button1.ForeColor = default(Color);
Button1.UseVisualStyleBackColor = true;
