You can simply use grid layout manager, just pass the context and number of columns in grid layout manager's constructor and in the constructor of your recycler view adapter pass the reference of array of images. Then set image on background in onBindViewHolder function of your adapter

Here is a sample code:

GridLayoutManager gridLayoutManager = new GridLayoutManager(SharingPhotoActivity.this, 3);
            if (recyclerView != null) {
                recyclerView.setLayoutManager(gridLayoutManager);
                recyclerView.setItemViewCacheSize(0);
            }
            mAdapter = new imageRecyclerAdapter(SharingPhotoActivity.this, bitmapList, compressUriList, mStorageRef, bitmapModels);
            recyclerView.setAdapter(mAdapter);

You can use Color Pallette and extract color of each image. Each image will be an item in recylerview.
