if there was a purple or teal one I would buy it in a heartbeat. Hell, even navy.
Annoys me to no end that fun colors are limited to the "cheap" lines like the Neo, Air, and Duo while Pros are boring. If I'm spending $4k on a laptop then why can't I get it in green? It genuinely makes no sense.
But you can also get a "Pro" phone in safety orange for some reason. It's not even consistent.
In the iPhone case it is consistent, they always save a particular colour for the Pro model only. Purely to let people signal they have the Pro, and it has to be different every year, so they can signal they have the newest Pro.
