There are bound to be viewers that show the 3 directions and allow you to set a colormap to your liking.

If your data is something like (x,y,spectra), you could try:
imagesc(your_data(:,:,1));
If your data is like (spectra, x, y) you could try:
imagesc(squeeze(your_data(10,:,:)));

We just need to switch what's being labeled as x and y in the code I gave you remember that matlab uses row-major dimension ordering.
[Ydim,Xdim,Spectra_dim]=size(your_data);%should be Ydim = 984, Xdim=740, Spectra_dim=224.
[X Y Spectra]=meshgrid(1:Xdim,1:Ydim,1:Spectra_dim);%each array shoudl be 984x740x224
figure;
surf(squeeze(X(1,:,:)),squeeze(Y(1,:,:)),squeeze(Spectra(1,:,:)),squeeze(your_data(1,:,:)),'EdgeColor','none');
hold on;
surf(squeeze(X(end,:,:)),squeeze(Y(end,:,:)),squeeze(Spectra(end,:,:)),squeeze(your_data(end,:,:)),'EdgeColor','none');
surf(squeeze(X(:,1,:)),squeeze(Y(:,1,:)),squeeze(Spectra(:,1,:)),squeeze(your_data(:,1,:)),'EdgeColor','none');
surf(squeeze(X(:,end,:)),squeeze(Y(:,end,:)),squeeze(Spectra(:,end,:)),squeeze(your_data(:,end,:)),'EdgeColor','none');
surf(squeeze(X(:,:,1)),squeeze(Y(:,:,1)),squeeze(Spectra(:,:,1)),squeeze(your_data(:,:,1)),'EdgeColor','none');
surf(squeeze(X(:,:,end)),squeeze(Y(:,:,end)),squeeze(Spectra(:,:,end)),squeeze(your_data(:,:,end)),'EdgeColor','none');

To control the orientation of the image, read the documentation for 3-D camera control:
Specifically read the documentation for view:
There's also a button in the graphic windows to manually orbit the camera around.
As for the color, please study the documentation for colormap and caxis
As always when reading the documentation, pay attention to links to other function and the see also section to see related functions. Following these links will lead you to examples of related tasks and provide a broader view of the tools you have at your disposal.
