How to get different color with respect to an figure.

I have two figures first one with different colors and second one with one color.

Could anyone help me how to get the second figure with different color with respect to first figure.

code:

first figure

plot(PPP(:,1),PPP(:,2),'k*')
hold on
for cc=1:centroids
plot(PPP(c(:,a)==cc,1),PPP(c(:,a)==cc,2),'o','color',cluster_colors{cc});
end

second figure

figure
 plot(1:N_UE,A,'-k*')

could anyone please help me on this.

? Your question is not clear ?

Do you want some code that examines a given figure (figure 1) and figures out all the colors that are used in it, and then calculates a color that has the maximum RGB difference relative to the colors used in the first figure, and changes the color of the line in the second figure so that it looks as different as possible in color from any of the colors used in the first figure ?? Or should the difference be computed in HSV? Or in L*a*b ?

the color of second figure should be the same with repect to first figure.

But with respect to the command used for plotting the second figure gives only one color.

Could you please help me to get the second figure with colors similar to first figure.

Of course the second figure only gives one color: you only plot one line and you tell it that the line should be black ('k') with a simple solid line ('-') with asterisk marker ('*')

It is not possible to have multiple colors in a single line() object.

It is possible to create a single line() object and to scatter() markers on top of it, but it is not clear that is what you want.

YOu should use the predefined colors to do that.

color = rand(6,3) ;

x = 1:6 ;
y = rand(size(x)) ;
figure(1)
hold on
for i = 1:6
    plot(x(i),y(i),'*','MarkerEdgeColor',color(i,:)) ;
end
figure(2)
hold on
for i = 1:6
    plot(x(i),y(i),'*','MarkerEdgeColor',color(i,:)) ;
end
plot(x,y,'b')
