serv. pyramid

I would try to put Pyramid instead of Service in red, since Service is the generic description and the word that describes/identifies the company from others is "pyramid" I would swicht the color. I am also not sure of the grey-bluish hue you use d for the rest of the logo but I think 2 colors is fine for this design, just go and see if there´s other that match better what your client want to comunicate.
