Rescaling RGB for imagesc

I have a colormap:

BeautifulColorVector =

0.3735 0 0.7500

0.2490 0 0.5000

0.1245 0 0.2500

0.0700 0.0700 0.0700

I made this to create a 2x2 matrix with beautiful colors by imagesc.

How can I rescale the colour in a way that true colors appear by imagesc function?

BeautifulColorVector = [
    0.3735         0    0.7500
    0.2490         0    0.5000
    0.1245         0    0.2500
    0.0700    0.0700    0.0700];

img = [1 2; 3 4];
imagesc(img); colormap(BeautifulColorVector)
