Thank you for the clarification! I apologize for the oversight regarding duplicates and the specific channel quantization. Let’s create a new 16-color palette that adheres to your constraints, ensuring that there are no duplicates, the first entry is black ( #000000 ), the last entry is white ( #ffffff ), and each color channel is set separately using the quantization of 00, 55, aa, or ff.

Here’s the updated palette:

This palette maintains uniqueness for each color, starts with black, and ends with white, while adhering to the specified color channel quantization.
