In my Matlab code, I am trying to merge two graphs in each iteration of for loop. I want the color of graph generated to be same for an iteration, but varying color with iteration

One approach, notice how I used color property of plot:
x=1:10;
y=2*x;
for i=1:numel(x)
a=rand(1,3);
plot(x(i),y(i),'Marker','o','color',a);hold on;plot(x(i)+1,y(i),'Marker','o','color',a);hold on;
end

Change this line
plot(x(i),y(i),'Marker','o','color',a);hold on;plot(x(i)+1,y(i),'Marker','o','color',a);hold on;
to
plot(x(i),y(i),'Marker','o','color',a,'DisplayName',num2str(i));hold on;plot(x(i)+1,y(i),'Marker','o','color',a,'DisplayName',num2str(i));hold on;legend('show');

Is there a way to simply save information of colors form plot, or reset the "Matlab color ordering"?

Use the property Color when you plot the figure and the colormap of your choice (parula post 2014b, jet before)
g = randn(12,150);
h = randn(12,150)+5;
figure;c_map = parula(12);
for iR = 1:12
hAx=subplot(4,3,iR);hold(hAx,'on');
plot(g(iR,:),'Color',c_map(iR,:));
plot(h(iR,:),'Color',c_map(iR,:));
end

You can use a random function as follows:
for i=1:1:10
v = rand(3,1);
plot(X1,Y1,'Color',v);
hold on
plot(X2,Y2,'Color',v);
end
