1 month ago Regarding the color contrast for 580 compliance, I verified the the 2 URL links. Most of those elements are fine with 508 compliance checker - ANDI. However, we may need to be careful to use the closest colors in the charts or maps. We want to make sure we have enough contrast ratio. I recommend development team to add this link to your Chrome or Edge browser to check it as you go - https://www.ssa.gov/accessibility/andi/help/modules.html#cANDI
Is your feature request related to a problem? Please describe.
Should the colors and symbology used for TADA maps be consistent?
TADA_ColorPalette() TADA_ViewColorPalette()
The TADA color palette is color blind friendly. Hopefully, it is also already 508 compliant. @erg-hzhou offered to check this for us. Once the colors are finalized, we will use this palette for all new TADA figs and maps.
In addition, let's review the symbology used within TADA maps. TADA_OverviewMap() TADA_ViewATTAINS()
@renaemyers is also working on a new site review map function: https://github.com/USEPA/TADA/issues/464 so this issue is relevant to the colors and symbols we decide to use there...
Here are other options for map symbols: https://designsystem.digital.gov/components/icon/
Describe the solution you'd like
Ensure colors are 508 compliant. Colors and symbols can be consistent across maps/figures where possible (but not always necessary).
Describe alternatives you've considered
Some maps/figs may require more specific colors or symbols thus consistency is not as important and making sure they look good and are user friendly.
Reminders for TADA contributors addressing this issue
New features should include all of the following work:
[ ] Create the function/code.
[ ] Document all code using comments to describe what is does.
[ ] Create tests in tests folder.
[ ] Create help file using roxygen2 above code.
[ ] Create working examples in help file (via roxygen2).
[ ] Add to appropriate vignette (or create new one).
