Hi DAVID,
Thank you for your review of the Delta Faucet CASSIDY™ Bathroom Faucet MODEL#: 597LF-CZMPU. Please accept our sincere apology for the inconvenience you are experiencing. We are always happy to assist. Quality is very important to us and our products undergo rigorous testing to ensure high-quality performance.  
We’re sorry to hear that you’re not completely satisfied with the finish on your new Delta product. We attempt to minimize variations in color by utilizing certain control methods. However, differences in sizes, shapes and materials of individual faucet parts can produce variations in color that can sometimes be noticeable to the human eye, despite the controls we have in place.
We appreciate your business and look forward to continuing to serve you. Please contact us directly if you have any further questions.   
Best Regards,  
Kelley
