Indeed, how can someone like Asobo make such a mistake!!! How can you!!!
Look up the FAA runway markings document. The runway exit path you’re talking about should indeed be alternating colors, but it should be green and YELLOW, not orange!!!
And are the screenshots you’re showing based on X-Plane’s default airport markings, or are they from some third party airport scenery?
With all due respect, please make sure you do your research before offering criticism.
