When I function imshow to display an image and change the default color, everything is okay. However, when I save the figure to pdf format, the color of white pixel is not correct.
set(groot, 'DefaultFigureColor', 'blue');
set(groot, 'DefaultFigureInvertHardcopy', 'off');
p = phantom();
figure(1)
imshow(p)
saveas(gcf, 'phantom.pdf');
This is the result of Figure 1.
This is the result in file 'phantom.pdf'.

I don't know if this helps you, but try export_fig . it served me well so far when I wanted to export things to pdf.

The cause is that renderer we use to print is switched to painters. You may use -opengl flag with print command
print(gcf, 'phantom', '-dpdf', '-opengl')
