Contact info on yellow vs white letters

[Cesar Romero]

So as I see it, white letters are intended to give a more "corporate" and professional impression which attracts certain potential sellers whereas yellow letters give a more personal touch that may hit other types of sellers. That said, should the means of contact provided also vary? E.g. I have a phone number that gives a detailed corporate-sounding description of my service before directing the caller to a live operator with questions ready. Should I only use that number for the white letters and, instead, use just a regular personal voice mail contact for the yellow letters? And apologies if this has already been discussed. Thanks.
