What is the color spec for default blue?

i.e. this blue:

----

I tried:

c = repelem([0 0.4470 0.7410],length(X),1);
%scatter(X,Y,c)
scatter(X,Y,[0 0.4470 0.7410])

but if fails with message:

Error using scatter (line 76)
S must be a scalar or a vector of the same length as X.

Error in scaling_experiment_loss_vs_gen_errosr_normalization (line 65)
scatter(X,Y,[0 0.4470 0.7410])

It depends on what you call "color spec".

figure,
axes;
LineH = plot(rand(1, 10), 'o')
get(LineH, 'Color')

>> [0 0.4470 0.7410]

Or maybe you mean:

plot(1:10, rand(1, 10), 'b')
                        ^^^

? If this does not help, please edit the question and add more details.

I tried 'b' but its the wrong tone... yea I mange to get that vector but I cant use it for some reason...

[Brando Miranda]

c = repelem([0 0.4470 0.7410],length(X),1);
scatter(X,Y)

fails

[Jan]

"fails" does not allow to understand, what you observe. "c" is not used in your scatter command. So perhaps this is a typo only?

X = 1:10;
Y = rand(1, 10);
c = repelem([0 0.4470 0.7410],length(X),1);
scatter(X, Y, [], c)

Works under R2016b.

Answer 2

[Brando Miranda]

c = [0 0.4470 0.7410];
scatter(X,Y,'MarkerEdgeColor',c)

finally worked

[Brando Miranda]

h = scatter(X,Y)
c = get(h,'Color')
c{1}
c{2}

You can get all the default colors like this:

% Get the initial set of default plot colors.
initialColorOrder = get(gca,'ColorOrder') % Initial

You can change that order, and my attached demo shows you how.
