Importance of PLA color?

[Dloranger]

I see you run a grey and black color schema, curious if this is necessary, or if it was an arbitrary decision? I understand the value in keeping the two styles the same, makes total sense, just curious if I need to go buy grey and black PLA specifically or if other colors would work. I am thinking to have a coded system for different types of parts, say white body with blue top for paper taped resistors, white body with red top for paper taped capacitors, etc, etc. Not sure I will end up there, but I will end up using a lot of different components and sizes over time so having them somewhat organized can only help my cause.
