“White Collar” in Spanish

I’m wondering if there is equivalent to white-collar that is similar to meaning in English.

Example: “That man has a very white-collar appearance but his personality is that of hungry snake.”

If there is also a way to say to “Blue-collar” it would be much appreciated, as a side note: I’m re-learning Spanish as it was initially my first language when I was younger but stopped speaking it primarily during pre-school and kindergarten, I’m now relearning it again as I am a High School Student.
