Where in the axes properties (or elsewhere) is the "pointer" on the next color of ColorOrder ?

The command
hold all
holds the current line color in the ColorOrder, so that following plot commands continue cycling through it. This seems to be only a feature of high-level-functions like plot. However, there must be a change in the 'axes properties' (besides the 'NextPlot' property), something like a pointer telling the next plot, which color to be used.
My problem is that I use low-level-function 'line' and want to add another line(s) in the next color of ColorOrder. Is there a more simple way to realize this instead of getting the existing line objects color by some functions as get,findobj and then choosing a non-used color for current line, which could not really considered as cycling.
Thanks.

Maybe not exactly what you wanted but a workaround:
fH = figure;
aH = axes;
lH = plot(rand(10,1),'r');
your_colors = get(fH,'DefaultAxesColorOrder');
colorIdx = find(ismember(your_colors,get(lH,'Color'),'rows'));
nextColorIdx = mod(colorIdx + 1, size(your_colors,1));
nextColor = your_colors(nextColorIdx,:);
I think creating your own custom color order and cycling through it would be better. The snippet I gave you will not work if the color of the line you plot is not in the default colors.

getappdata(gca, 'PlotColorIndex')
When it is non-empty, it is the index of the next color to plot.

If I recall correctly, line() does not cause cycling through the color order; it is functionality built into plot()
