Update

As of MATLAB R2023a you can use the colormap sky

cmap = sky(256);

x = linspace(0,.5*pi,500)';

plot(sin(x).*linspace(0,1,20))

colororder(sky(20))

Prior to R2023a

Here's the colormap used by heatmap that spans from light to dark blue

n=256;
cmap = [linspace(.9,0,n)', linspace(.9447,.447,n)', linspace(.9741,.741,n)'];

x = rand(10, 20) + (1:10).';
figure;
axes('NextPlot', 'add');
color1 = [0.5, 0.5, 1];      % Set colors according to your definition of
color2 = [0,   0,   0.5];    % "light blue" and "dark blue"
m      = linspace(0, 1, 10);
for k = 1:10
    color = color1 * m(k) + color2 * (1 - m(k));
    plot(x(k, :), 'Color', color);
end
