Error while using dot notation

I execute the following code but I get the error "Insufficient number of outputs from right hand side of equal sign to satisfy assignment." I am using MATLAB R2016a.

plot(rand(3))
lgd = legend;
c = lgd.TextColor;
lgd.TextColor = 'red';

It works correctly if you provide legend with something to do:

plot(rand(3))
lgd = legend('Data');
c = lgd.TextColor;
lgd.TextColor = 'red';
