Add colorblind friendly color scales #20437

Open scaidermern opened 3 months ago

scaidermern commented 3 months ago

Describe the idea (required)

Split off from #20432: It would be nice if OsmAnd would include more color schemes by default, especially color scales for colorblindness.

As a source for nice colorblind-friendly color scales, please refer to the following sources: https://davidmathlogic.com/colorblind/ https://www.nceas.ucsb.edu/sites/default/files/2022-06/Colorblind%20Safe%20Color%20Schemes.pdf https://github.com/sjmgarnier/viridis/ https://colorbrewer2.org/#type=sequential&scheme=BuGn&n=9

Well I think we need just different scales it's not about color blindness it's also about different data. Even with normal color vision, you can't distinguish some shades cause your data is too dense around average value.

Yes, there are many different reasons for adding additional color scales. Maybe do this step by step, starting with the easiest tasks. There are already predefined color schemes for colorblindness available, adding them is probably easy :)
