How to code the colors in MATLAB?

Hey all,

I was just wondering how I can find the codes for colors in Matlab. Furthermore, what are the related commands in order to use them? e.g. how can I make a RED word?

Thanks a lot :)

Colorspec

Example:

plot(1,1,'*','MarkerEdgeColor','r')

or

plot(1,1,'*','MarkerEdgeColor',[1 0 0])

does the same thing

More red examples

%figure with red background
set(figure,'color',[1 0 0])

and

%axes with red background
set(axes,'color',[1 0 0])

Finally red text

text(0.1,0.1,'Hello MATLAB user','color',[1 0 0])

If you are looking for red text on the command line you must use cprintf

Hey Paulo, Thanks so much for help :)

May I ask you another related question?

Suppose we have a picture. All coordinates of the pixels have already been imported to Matlab (let's say a 600x800). If I want to change a particular voxel(s) of this picture to red or any other color what would be the solution?
