Colorization of REST verbs

Simple question, is there a standard accepted in the industry for colorization of REST verb in UIs? I ask because we are implementing a new API and trying to use Postman extensively for testing and it’s quite confusing when our validated Swagger doc shows this versus Postman:

Swagger POST=green, GET=blue,PUT=orange
Postman POST=orange, GET=green, PUT=blue

at least DELETE is red in both…
