In the new version of OBM there is a Light and Dark Mode, The states are currently working on looking through and Upgrading all of their information to ADA compliance for the new WCAG (Web Content Accessibility Guidelines) it would be helpful if ORD had a Toggle for different communities of Need. Perhaps starting with a Colorblind view similar to a Light/Dark mode.
Thanks for the suggestion. I'm moving this to MicroStation Ideas for further consideration as they'd need to implement it. Also, Windows does have built-in colorblind options, which I would recommend checking out.
