How do I reduce the opacity of a real code paint scheme - and if I'm using "user input" statements to control the color - how do I see what the color actually is without trying each and every color?
Is there some kind of color name available when I mouse over the colors?

Look into the vb.net Color.FromARGB call. The Alpha value is the opacity. 255 is opaque, 0 is transparent.

I don't understand how to use this?
Look into the vb.net Color.FromARGB call.
When I look at the drop down list of colors - they have names - where do I get the RGB values?
It would be better if you can give me a detailed example - I get the "A" = opacity part but don't have aclue as to how to use what you said

The coloring is a standard VB.net syntax. The drop down list is a short cut to pre-defined colors (RGB values). R = Red, G = Green, B = Blue. Color.Red = Color.FromARGB(255,255,0,0). Color.Blue = color.FromARGB(255,0,0,255)
You can use the built in windows program "Paint" to get RGB values for colors or you can use an online color picker.
