background image brightness changed after displaying contour

Hi, I am using function 'contour' to display my image segmentation result on a grayscale CT image. Then I noticed that the background image looks brighter after the contour is displayed on the screen.

This is my code:

imagesc(imgslice);colormap(gray); %imageslice is a 2D double-format image

hold on;contour(imgbw,'Color','r');%imgbw is the segmentation binary mask image
hold off;

I am preparing to present the original image and the contour image so this inconsistency may be attacked by the examiners.

I am hoping someone here could help me! Thanks a lot!!
