How to change the color of a single point in a scatter plot?

I am plotting points:

x = [ 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 4 4 4 4 4 5 5 5 5 5];

y = [ 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5];

plot(x,y,'*')

I would like to change the color of just an individual point, how do I go about it?

x = [ 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 4 4 4 4 4 5 5 5 5 5];
y = [ 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5];
plot(x,y)
hold on 
scatter(x(7),y(7),'r')
hold off
