My original image is with colour. I read the image file and display it, then I got a grey scale image. Does anyone know how I can load the image without change the colour scale? My code is like this: clear; close all;
I = imread('abc.gif')
figure, imshow(I);

Don't name it I - that's a bad name - hard to tell the difference between I (upper case i), and l (lower case L), and 1. Plus it's not very descriptive.
Try this
[indexedImage, colorMap] = imread('abc.gif');
imshow(indexedImage);
colormap(colorMap);
colorbar;

You have it displayed 3 times. Each figure is using a different colormap.
