interior color for a black truck?

[Iron Hauler]

Well I have my 70 4x4 in the paint shop now and should be done in a couple weeks. All my of my other old trucks I've went with black interior [dash pad, seat, door panels] but this is the first time painting a truck black. It just seems like too much to go black inside and would like some color but not real big contrast like white would be. What are some good choices? I remember seeing red once on here and maybe blue, any suggestions? I want to stay with all stock type peices so colors that are being reproduced can be used.
