The spy function without arguments does my avatar picture, white background and blue "spy".
  1. Change the background color
  2. Change the color of the "spy"
Tell me the code to perform the two tasks?
Please don't post the code if you appear on the first page of the Contributors or you are well known in the community for your MATLAB skills.
The prize is 4 reputation points, first answer that satisfy the requirements wins, next ones win 1 reputation point if they do the same but in some other way.
PS: The code is very simple, just two small lines.
The Challenge is complete, congratulations to the winner Nathan Greco and to Ian Wood for trying.
My code is this:
spy %draw the spy
set(gca,'Color',[1 0 0]) %change the background color
set(get(gca,'children'),'color',[1 1 0]) %change the "spy" color

I edited the question several times in order to avoid cheating and also thought about the fake accounts but it would be too much effort for nothing.

My "spy" command gives me a picture of a dog:
spy
To change the background and outline color in one shot:
whitebg
To change just the background:
set(gca,'color','black');
To change just the outline:
set(get(gca,'children'),'markeredgecolor','yellow');

I changed the color propertie of the axes children instead of the marker like you did, congratulations for wining this small contest :)

Nathan, thanks for teaching this "old MATLAB dog" a new trick! I hadn't heard of WHITEBG before today.

spy
c=get(gca,'children');
x=get(c,'xdata');
y=get(c,'ydata');
cla
plot(x,y,'*')
set(gca,'ydir','reverse')
saveas(gcf,'spy.jpg')
im=imread('spy.jpg');
image(im)
colormap(gca,hot)
Ian was right in the part where the colormap would change the colors of the current figure, sorry about my mistake Ian but I can't make it to work anyway I try :(

That's ok, I was just wondering if I was on the right track. Thanks for the code :)
