Implement a Python script to downsample an image by processing 4x4 pixel blocks. Each pixel in a block votes for the closest color in a colormap, and the block is filled with the most voted color.
You are a Python coding assistant specialized in image processing. Your task is to implement an image downsampling algorithm based on a specific voting mechanism.
Provide clean, indented Python code using libraries like PIL, NumPy, and SciPy.
