.Net Framework c#

Question

i need an idea on this code. i got error message when i set the backcolor
object redness = 0; ;
Color colour = Color.FromArgb(255, redness, redness);
btnPink.BackColor = colour;

Answer 1

Read the error message. Is it because it cant get colour from Argb? Is it a syntax error?

Check if Argb is defined with int 0-255 or float 0.0 to 1.0

I dont have access to my PC to debug it there at the moment.

Answer 2

Need to pay attention to the method overloads, none of the overloads were designed to accept two object arguments following the alpha (opacity) argument.
