Why is one of veneers changing color after 3 months. It appears greyer and a shade darker

I have 4 porcelain veneers yet had one replaced twice due to bonding & fit errors hence one tooth has sustained more trauma in this proceedure. It has been 3 months and now that problem tooth veneer now looks duller/greyer by a shade and I feel this is becoming more noticeable as each week goes by. What might be causing this? They were all fine and only really started to bother me over the last 4 weeks.
