Thank you for your clarification! Let’s create a new 16-color palette that starts with black ( #000000 ), ends with white ( #ffffff ), incorporates colors specifically from the eighth palette, and ensures there are no duplicates while adhering to the quantization constraints.

Here’s the corrected palette:
