How to add legend in CIE diagram

I have four points that I want to plot on CIE diagram. I am using the following command:

plotChromaticity
hold on
scatter([x_1 x_2 x_3 x_4],[y_1 y_2 y_3 y_4])
hold off

Now I want to add legend for these four points. For example: 'red', 'blue', 'green', and 'yellow'.

How can I do that?

plotChromaticity
hold on
x = rand(1,4);
y=rand(1,4);
name =["red", "blue", "green", "yellow"]

name = 1×4 string array
    "red"    "blue"    "green"    "yellow"

for i=1:length(x)
    hs(i) = scatter(x(i), y(i),  'DisplayName', name(i));
end
hold off
legend(hs)
