how can i modify the color of specifc vector and add a label in quiver3

Hi to everyone, i wolud like to understand if I can change the color of quiver3 arrows and add a label.

q_w=quiver3(zeros(3,1),zeros(3,1),zeros(3,1),vec1,vec2,vec3);
q_w.LineWidth=3;
q_w.AutoScaleFactor=8;
% x-y-z Red-Green-Blue

Try this:

vec1 = rand(3,1);
vec2 = rand(3,1);
vec3 = rand(3,1);
for k = 1 : length(vec1)
	q1 =quiver3(0,0,0,vec1(1), vec1(2), vec1(3), 'Color', rand(1,3));
	hold on;
	q1.LineWidth=3;
	q1.AutoScaleFactor=8;

	q2 = quiver3(0,0,0,vec2(1), vec2(2), vec2(3), 'Color', rand(1,3));
	q2.LineWidth=3;
	q2.AutoScaleFactor=8;

	q3 = quiver3(0,0,0,vec3(1), vec3(2), vec3(3), 'Color', rand(1,3));
	q3.LineWidth=3;
	q3.AutoScaleFactor=8;
end

Use text() to add a label.
