Hi Adam @argyleink I would like to respond to a couple things that you mentioned in the meeting, that I see listed in the IRC log. > _argyle: Say apca comes out and is stable,_ The current base algorithm for apca-w3 has been in public beta since Feb 2021, and that base algorithm has not changed since then, **over two years**. Thus far `0.0.98g4g` has shown to be best for a simple pair-of-colors solution for sRGB self-illuminated displays. > _argyle: apca3 is still not producing good results yet, still a few years out_ ### _YIKES!!_ **OK you have my attention.** There have been no issues filed nor discussions in any of the repos reporting this. I would really like to dig down and understand what problems you are seeing. First I'd like to establish that you're basing this on the current version of the algorithm, the base algorithm is identified as ` 0.0.98g4g `, and while there are a lot of implementations out in the wild due to the popularity, many of them are unfortunately flawed, using incorrect values or implementations. The *only* canonical tool is: **https://apcacontrast.com** The _only_ canonical repos are: **GitHub:** https://github.com/Myndex/apca-w3 **npm:** ` npm i apca-w3 ` ### Other tools: There are a few third-party tools that are pretty cool, but should not be used for evaluation I have a number of caveats, as they are generally not complete implementations. Also, there is another Myndex hosted tool that is only for experimental work, at `myndex dot com/SAPC/` but it **should not be used for general evaluation** as it is used for live experiments and results may vary. It has been brought to my attention that **Chrome** and **Edge** are still using incorrect values and incorrect code, and therefore are **not APCA** and should not be relied upon for any purpose, nor used for any form of evaluation. And I have been trying to chase down some of the developers of some implementations that are using the wrong code in association with the wrong look up tables. All of these kinds of problems I hope you recognize are simply a factor of having an open and public beta period. ---- ### That Said Nevertheless, if you are finding problems of any sort with the current version, **I really need to hear about it**. Please. I would like to talk to you about what results you found were "not good" or that are problematic, and the circumstances and characteristics of what you perceive as not usable. If you'd like to contact me privately, my DM's are open on Twitter at https://twitter.com/MyndexResearch You can also reach me via the email which is listed here on my profile. Thank you for reading, I look forward to discussing this with you soon.
