How to change the color of the most recent plot point?

I am trying to make something that will change the color of the most recent plot point.
This is my code so far:
%% Clear
clear;
close all;
clc;
%% matrix creation
b = [100,25,50,25; 50,50,50,50; 20,125,5,50; 5,10,15,170];
%% plot
times = length(b(:,1));
for k = 1 : times
R = b(k,1) + b(k,2);
L = b(k,3) + b(k,4);
T = b(k,1) + b(k,3);
B = b(k,2) + b(k,4);
sum = b(k,1) + b(k,2) + b(k,3) + b(k,4);
Rper = R/sum;
Lper = L/sum;
Tper = T/sum;
Bper = B/sum;
Hdist = 6.5;
Vdist = 4.25;
RHdist = Hdist * Rper;
LHdist = Hdist * Lper;
x = RHdist - LHdist;
TVdist = Vdist * Tper;
BVdist = Vdist * Bper;
y = TVdist - BVdist;
hold all
pause( 1 );
figure
plot(x,y,'o','MarkerFaceColor','k','MarkerEdgeColor','k')
xlim([-6.5 6.5])
ylim([-4.25 4.25])
ax = gca;
ax.XAxisLocation = 'origin';
ax.YAxisLocation = 'origin';
grid on
end

end
plot(x(k),y(k),'o','MarkerFaceColor','r','MarkerEdgeColor','k')
xlim([-6.5 6.5])
ylim([-4.25 4.25])
ax = gca;
ax.XAxisLocation = 'origin';

grid on
end
