I’m glad we hit the bullseye! Now, let’s create the negative alter egos from -0 to -9 by inverting the color values of the original palette from 0 to 9. Here’s the new extended color palette, including both positive and negative values:

}

In this palette, I’ve created the negative versions from -0 to -9 by inverting the colors from 0 to 9. If you have any further modifications or questions, feel free to ask!
