How can MarkerFaceColor be set to take on whichever color MarkerEdgeColor is by default?

Hello John,
This can be achieved by setting the line properties in the plot.
The 'MarkerEdgeColor' is the outline color of the marker. Its default value is 'auto', which uses the same color as the 'Color' property of the line. This value can be accessed using the dot notation on the line object.
The following is an example code snippet:
l = plot(x,y,'o');
l.MarkerFaceColor = l.Color;

Try this:
x = 1:5;
y = rand(1,5);
l = plot(x,y,'o', 'MarkerSize', 30);
l.MarkerFaceColor = [.6, .2, .9]; % Change color from default to purple

You can also set the color in the plot call
myColor = [.6, .2, .9]; % Change color from default to purple
for k = 1 : whatever
x = whatever
y = whatever
plot(x, y, 'o', 'MarkerSize', 30, 'Color', myColor);
end
Or you can use scatter and use one of the inputs to specify the colors for all of the datasets in advance.

You can set the MarkerFaceColor inside the plot call just like you can set Marker, MarkerEdgeColor, etc. They're all properties of the line.
c = [0.25 0.5 0.25];
plot(1:10, 1:10, ...
'Color', 'r', ... red line
'Marker', 's', ... square markers
'MarkerEdgeColor', c, ... marker edges are green
'MarkerFaceColor', 1-c); % marker faces are purple
