How to | Add Transparency to Plots
Transparency is useful in plots when you need an unobstructed view of multiple components of one plot, or simply want to lighten a single plot component against a white background. Mathematica uses the graphics directive Opacity to apply transparency to graphics objects. Opacity can be used with most visualization functions.
Here is a 2D plot:
 Out[50]=
Use the PlotStyle option with Opacity to make the plot 70% transparent:
 Out[51]=
Here is a 3D plot:
 Out[1]=
Make the plot 60% transparent:
 Out[2]=
Add different transparency settings for plots of multiple functions:
 Out[54]=
Here is a 2D region determined by two inequalities:
 Out[55]=
Make the plot 50% transparent:
 Out[56]=

Use Opacity to see the inner parts of a plot:
 Out[4]=
Use the ContourStyle option of ContourPlot3D with Opacity:
 Out[5]=

You can also add transparency to graphics.
Make a 75% transparent disk:
 Out[21]=
Opacity can have values between 0 and 1, with 0 corresponding to perfect transparency:
 Out[42]=
Use Opacity with a color:
 Out[41]=

Opacity interacts well with other Mathematica functions:
