Try something like this —
x = 1:10;
y = rand(size(x));
stem(x, y)
hold on
stem(x([1 3 5]),y([1 3 5]),'g', 'MarkerEdgeColor','b')
hold off
It changes the stem colour to green, and keeps the marker colour blue.
It is also possible to change the other properties of the chosen (and other) stems and markers.

x = (1:66);
y = randn(1, 66); % your data
figure; hold on
stem(x, y, 'r');
i1 = [39 53 59];
stem(x(i1), y(i1), 'g');
