Hi @chinmaychahar can you update the OP with before/after screenshots? Also we will need to update both gallery thumbnails to go along with this change. Some of the recent merged PRs for accessible palettes would be a good place to look for the required changes e.g. #12946 Let me know if you need a more detailed reference!

HI @bryevdv I've updated the PR with the before/after screenshots. As for the thumbnail, I have the original png but resizing it to the desired 300x300 is leading to reduced quality. Any suggestions on how I can tackle that?

Can you post it for us to examine? The images are just for gallery thumbnails so they are intended to be small / low quality.

[chinmaychahar]

@bryevdv I just updated the new thumbnails. Let me know if they need any changes!

Also, if there are any changes required to the palette too.

[bryevdv]

I wonder if swapping the colors (having the dark blue under the l line, and orange over) would be slightly more aesthetically pleasing.

[chinmaychahar]

Sure @bryevdv that looks something like this:

I am happy with the new colors. The original colors were taken from wherever I took the original idea from, and the new colors seem much better.

[bryevdv]

@chinmaychahar seeing the swapped version, I don't actually have any preference. Whichever you want to use is fine!

[chinmaychahar]

I'm fine with the current version if that's alright. I've updated both the code as well as the thumbnails!

[bryevdv]

Thanks @chinmaychahar !
