Guidelines & Standards
This section is focused on the European area because I am a citizen of the EU.
For more information, see my short blog post about the European Accessibility Act: https://mic.st/blog/european-accessibility-act-in-short/

You can quickly find a solution for a lot of use case with short explanations, nice graphics and code snippets. Also, it’s open source! You can find the github repo here: https://github.com/Orange-OpenSource/a11y-guidelines.|
|https://www.w3.org/WAI/WCAG21/quickref/||The WCAG is the guideline when it comes to accessibility. The most recent version is 2.1. However, the guidelines are focused on web. Therefore, some rules are not directly applicable to mobile or need interpretation. The version 2.2 of the guidelines is currently in the making and should include more mobile related topics.|

The standard is of importance together with the European Accessibility act (https://ec.europa.eu/social/main.jsp?catId=1485&langId=en). This norm also refers to WCAG.|
The official documents can be difficult to digest and to apply. Therefore, I would rather start working with simpler guidelines that refer to the official ones.

There are tools that can help building more accessible products (i.e conform to standards like EN 301 549).
Keep in mind: You should never solely rely on tools or automated testing.
Actually, there are dependencies and services promising automated conformance or something like that. This might work for simple things like spotting violations of color contrasts or checking for touch areas. It will get really difficult for more complex requirements like understandable user flows.

However, it is a little bit more advanced compared to similar palette generators. I would recommend to create a palette in an easier one (e.g. coolors.co or Color Hunt) and improve it using this one.|
