Off-topic, kinda related:
Caltrans used Omaha Orange, similar to Kubota orange, for decades. A cost effectiveness study found this custom color is more expensive to manufacture and is not used on any OEM equipment so everything ordered by Caltrans got custom-painted at additional cost before delivery. Plus it fades.
That study recommended a change in specifications to ordering new equipment in plain OEM white with added vinyl decals or striping as needed.
