Combining 6 images without discoloration

I tried combining multiple smaller images with a Background.

In the resulting image the background is just fine, but the smaller images that are added in don't have the right color .

Startimage((Py-12):(Py+11), (Px-12):(Px+11)) = Ppic(1:24,1:24);

This line puts Pacman into the Picture according to his Posisition and animation state.

The desired image looks kind of like this:

How does one go about solving this problem ?

Edit : All the files have now been attached. I am sorry.

Edit2 : Cut everything unrelated to my question out and reuploaded.

Thank you for your time and consideration .

Attaching the images and reading this would be a good start.

Your "gameimage" variable is a 3D RGB color image but you're not assigning any colors. You're treating it like it's a grayscale 2D image, which it's not. You'll have to assign all three color channels.

Thank you ! It works. I just needed to change

Startimage((Py-12):(Py+11), (Px-12):(Px+11)) = Ppic(1:24,1:24);

to

Startimage((Py-12):(Py+11), (Px-12):(Px+11),1:3) = Ppic(1:24,1:24,1:3);
