Would it be possible to change this greyscale picture into a other color scale like in the two images? I tried some codes to make the binary into a color but i am trying to have something more clear to look than greyscale... Thank you

I don't think MATLAB has a blue scale colormap. You could do something custom, like the following. I'll use camerman for illustration:
I = imread('cameraman.tif');
imshow(I)
n = 128;
blueMap = [zeros(n/2,1) linspace(0,0.5,n/2).' linspace(0.5,1,n/2).';...
linspace(0,1,n/2).' linspace(0.5,1,n/2).' ones(n/2,1)];
figure()
imshow(I)
colormap(blueMap)
imshow(I)
colormap('copper') % or parula, hsv, bone, jet, etc.
