Day 1 with JMP and a user wants to generate a point plot with 2 different colors for male and female:

The easy solution: use the Color Dropzone
The surprise: The Overlay does the same.
The second surprise: "Color" can do more than just "color":
For every entry in the legend, the user gets the possibility to define the Marker Style as well - as well as Size and Transparency.

A lazy user doesn't configure the colors manually - again and again for every single plot and subplot.
One alternative (which I use just very rarely): row states to specify Colors and Markers.

The disadvantage:
the legend in Graph Builder doesn't fit.
Another alternative (which I prefer):
define suitable colors via Column Property: Value Columns
Pros:
- meaningful legends - automatically (!)
- separate settings for every column (not via rows)
- I can control (via the Overlay and Color dropzone) where I want to use the setting - and for wich plots I DON'T want to use the setting : )
- I can overwrite the setting for individual entries via the legend right click menu

The 3rd surprise: there is no Column Property: Value Markers *)
Day 2 - the JMP user detects the subtle (and not so subtle) differences between the Color and Overlay Dropzones:
by adding a smoother:

Now, let's add Color to the plot
suprise 4: with Color via Color, there is just a single fit curve:

... this is when the user remembers surprise #1, tries Overlay, and falls in love with the Overlay dropzone:

So, for scatter plots there is no apparent difference between Color and Overlay - but for other plots it is !!!
And often Overlay is THE way to add color.
Another example:
vs.
Now let's generate another points plot - where there is a difference between Color and Overlay:
Color just adds color to the points, Overlay generates separate plots for every color, overlays them
- and by doing so: hides some girls. -> dangerous!
vs. 
Let's keep the plot as a stacked bubble plot, and with the findings from surprise #2, let's now define Markers for different values
... with the help of the Color Dropzone
