I got two permanent front crowns cemented recently. Front crown has a greyish appearance. Is it just me?

One on my central incisor and one on my lateral incisor. The lateral incisor matches the shade of my other teeth but my front central incisor feels greyish. The tooth stub below the crown is slightly grey and the lab technician molded my crown to better adjust the color shade given the situation.However after permanent cementation I feel like it is distinctly grey even when on the day of cementing it seemed fine.
