I am having a hexagonal 2-D plot. Is it possible to change the colors of the edges of this hexagon? Is there any way to choose the colors of a-b, b-c, c-d etc , differently ? Thanks.

Here is a code example of the plot.

vertex = ['a','b','c','d','e','f'];
ang = [0:pi/3:2*pi];
x=cos(ang);
y=sin(ang);
plot(x,y)
for j=1:6
text(x(j),y(j),z(j),vertex(j));
end

 Muhammad, you could do something like:
vertex = ['a','b','c','d','e','f'];
ang    = [0:pi/3:2*pi];
x = cos(ang);
y = sin(ang);
myOrder = [1, 0, 0    % red
           1, 0, 0    
           1, 0, 0    
           1, 0, 0    % red
           0, 0, 1    % blue
           0, 0, 1];  % blue
set(gca,'ColorOrder',myOrder,'NextPlot','replacechildren');
hold on
for jj = 1:numel(ang)-1
    plot([x(jj) x(jj+1)],[y(jj) y(jj+1)])
    text(x(jj),y(jj),vertex(jj));
end
