Hello there. The built in Color Vision Simulator introduced in ArcGIS Pro 3.0 is a wonderful feature. We'd love to see it expanded with an additional black and white option. This would have multiple benefits for map designers, including accessibility checks for achromatopsia, general contrast checking on colors, and previewing what a color map would look like if it happened to be photocopied by somebody (for example: in emergency management, field teams sometimes want to take paper maps into areas with no power or service), which would encourage or inspire the use of symbology that is not entirely color dependent. Thanks!
