OEM blue steering wheel in a green truck?

[I Have No Idea]

I just picked up this 69 LWB C10. Everything seems to be original from what I can see. I have seen a few pictures on here about a blue steering wheel in a green truck but haven't really found an answer. I am trying to keep the outside and interior as close to the factory styling as possible. If this truck came with the blue wheel ill keep it but if not ill do a green one.

Anyone have any info on this configuration?
