Looks like the text was added to the wrong file? It also looks like a "submodule" was accidentally added?

My reading of #28750 is that this should be about using color_sequences, which do not seem to be mentioned here.

text I have added in index.rst

Thanks for the potential contribution

This material can almost certainly not go on the main index page. There is already an entry for this in the Users Guide: https://matplotlib.org/stable/users/explain/artists/color_cycle.html Perhaps you would consider editing that in place, or finding a more suitable place for this.

Thank you for the feedback!
I appreciate the clarification regarding the placement of this content. Since there is already an entry in the User Artists Tutorial-color cycles , I’d be happy to enhance that section instead of adding a separate page.
To improve the existing documentation I can:
Expand explanations on what color sequences are and why they are useful.
Add clearer examples to demonstrate how to customize color cycles effectively.
Provide guidance on using color sequences in style sheets for accessibility and consistency.
Would these improvements align with Matplotlib’s documentation goals? Let me know if there are specific areas you'd like me to refine further. Looking forward to your guidance!

Thanks for the PR but besides the issues of location, these docs don't show the use of the color sequence registry and that is the issue that this new doc is intended to address.

Thank you for the clarification here
now understand that the goal of this documentation update is to showcase the color sequence registry rather than just general color cycle customization. Since my initial contribution in #28750 focused on explaining what color sequences are, how to customize them, and how to use different stylesheets for accessibility, I can refine it further to emphasize the color sequence registry specifically.
To improve this, I propose:
Adding an example that demonstrates how to use the color sequence registry effectively and
Highlighting the benefits of the registry over manually defining color cycles.
Adjusting the structure so that it directly addresses the intended purpose of this new doc.
please would this approach align with the documentation goals? I’d be happy to modify the PR accordingly!

Thanks for updating the PR status. My goal is to contribute meaningfully to the documentation rather than just using the CI. I appreciate the feedback and will refine my changes to better align with the documentation goals, particularly focusing on the color sequence registry as suggested.
would you please recommend any specific improvements to ensure the PR is in the right direction before marking it as ready for review again?

Adding an example that demonstrates how to use the color sequence registry effectively and

Yes, the PR will not even be considered for merging without this example

Highlighting the benefits of the registry over manually defining color cycles.

They serve different purposes and this PR should describe each one separately.

But like @rcomer said, please explain what these are to show that you understand these concepts.

My reading of #28750 is that this should be about using color_sequences, which do not seem to be mentioned here.

btw Thank you for the feedback! I understand that this documentation should focus on using color_sequences. I will review the existing documentation and make the necessary adjustments to ensure it properly covers color_sequences and
Also, I want to clarify that I have not used AI to generate this content—I have written and structured it based on my understanding of Matplotlib’s documentation and guidelines. I will go through the contribution guidelines again to ensure my PR aligns with the project’s expectations it would very helpful for me if you
Would suggest a specific section where you think color_sequences should be highlighted, or should I update the relevant Users Guide entry directly?

I have written and structured it based on my understanding of Matplotlib’s documentation and guidelines

The content of this PR does not show that you understand color sequences because it at no point specifically talks about what the color sequences are, nor how to create or use them.

Instead, these docs read like a generic mashup of existing documentation on color cyclers, which is why it reads like AI wrote it to @rcomer and me.

should I update the relevant Users Guide entry directly

The document @jklymak linked seems fine as a start.
