# 2-D Wavelet output changing when using 'figure' command in Matlab

I am having trouble understanding what is causing the problem to my Wavelet output when i am trying to display the image with the figure command.

I want to display both the Original image and its Wavelets decomposition, but when I'm using this code the original image is not displaying in a separate figure.

Here is my code,

im = imread('cameraman.tif');
imshow(im),title('Original Image')

[cA1,cH1,cV1,cD1] = dwt2(im,'bior3.7');
A1 = upcoef2('a',cA1,'bior3.7',1);
H1 = upcoef2('h',cH1,'bior3.7',1);
V1 = upcoef2('v',cV1,'bior3.7',1);
D1 = upcoef2('d',cD1,'bior3.7',1);

% To display the results of the level 1 decomposition, type:

subplot(2,2,1); image(wcodemat(A1,192));
title('Approximation A1')

subplot(2,2,2); image(wcodemat(H1,192));
title('Horizontal Detail H1')

subplot(2,2,3); image(wcodemat(V1,192));
title('Vertical Detail V1')

subplot(2,2,4); image(wcodemat(D1,192));
title('Diagonal Detail D1')


and the output of this code is just one figure with four plots (Digonal, Horizontal, Vertical details and Approximations)

but when I'm using figure command to display the original image in a separate figure,

 im = imread('cameraman.tif');
imshow(im),title('Original Image')
figure


it messes up the wavelet output,

Why does it happens that my output is changed to blue and red color ?

$$colormap(gray(256));$$
