I picked up a low pressure sodium lamp and am working on a Halloween demonstration. I’m hoping to make a display that appears one way under normal light, but looks totally different under the monochromatic 589nm sodium vapor light.

So basically, I’m looking to generate a color wheel where I pick a shade of gray and get a list of colors that would look that gray under sodium vapor light.

…I feel like there must be a Python library for thing or something…

Only realised when I went to reply. Using sync your video link doesn't show. Here it is for other sync users.

May be useful:
![Video about colors](https://youtu.be/fv-wlo8yVhk?si=cj3aaD8Ufm0Hlt6M)

So that's why, Sync tries to load this as an image, but there's no image link..

But apparently the link still works and is invisible in Sync.

Out of curiosity are you using quote or code tags? The HTML formatting in your post doesn't display correctly from kbin.

The Fediverse really needs to support standard markdown globally

Well I do get a code block so I'm not sure if that's Kbin-specific markdown but I also get a bunch of HTML inside it too. I can't view the raw comment like I could with RES, but I would suspect that the raw Markdown characters should be sent with the post, for the website to support in its style-specific way, or something. This seems more like someone's client or app inappropriately inserting display style information into the post? But I could be totally wrong, I'm not an expert

I'm just using the fenced code block markdown syntax.
