I have a figure with two data sets, one is blue and the other is dark green. I didn't specify the colors. I need to find out what the colors are so that when I make other figures and can keep the color constant, data set one = blue, data set two = dark green.
Everything I read online about color is for making color gradients, I just need to figure out what the default color values are. Thanks!

Here is some info to supplement what Image Analyst quoted from the help file:
h = plot(1:10,1:10,1:10,2:11);
c = get(h,'Color')
c{1}
c{2}
Here, I've used the plot command with an output, which is the "handle" to the plotted lines. Then I "get" the colors of those lines. "c" is a cell array with one element per line. Each element of c is an RGB vector (1x3) specifying the value of the color.

If you just want to know the default color before plotting, you can try
get(gca,'colororder')

From the help:
plot automatically chooses colors and line styles in the order specified by ColorOrder and LineStyleOrder properties of current axes. MATLAB supports four line styles, which you can specify any number of times in any order. MATLAB cycles through the line styles only after using all colors defined by the ColorOrder property. For example, the first eight lines plotted use the different colors defined by ColorOrder with the first line style. MATLAB then cycles through the colors again, using the second line style specified, and so on.
So you want to do something like:
set(gca, 'ColorOrder', myColorOrder, 'NextPlot', 'replacechildren');
where myColorOrder is an N by 3 array of your custom colors. See my demo for setting ColorOrder here: http://www.mathworks.com/matlabcentral/answers/19815-explicitly-specifying-line-colors-when-plotting-a-matrix
