Unable To See Shades Of Grey

(I’ve been a digital designer for quite a while now and surprisingly have little to no issue with customers. This particular customer had been extremely pleasant up until I was finalizing their product.)

Me: “All right, so, here’s the finished product! As soon as payment is sent, I can—”

Customer: “No. No, no, no!”

Me: “Is something wrong?”

Customer: “The grey! The grey is way too grey! It was fine before. What did you do?!”

Me: “Sir, I can assure you that between coloring the lines and now, I have not changed the colors.”

Customer: “You made the grey much too grey! Fix it!”

(I work for around 30 minutes using various saturation and colors to make it less “grey” for the customer. I eventually got frustrated and accidentally sent them the first image I had shown them on accident.)

Me: *realizing what I have done* “Oh, pardon me, sir, I think I sent you—”

Customer: “Yes! Perfect! This is what I wanted! Was that so hard?!”

Me: “Yes… Of course, sir.”

(He sent the payment and was perfectly happy with his “altered” product!)
