One is much deeper than the other

I painted one swatch of Benjamin Moore's Polo Blue on our white kitchen door. I painted another swatch of Benjamin Moore's Deep Royal Blue on the other half of the door. I asked my husband which color he liked the most. He looked at the doors. He looked at me. He looked at the doors. Then he asked; "Is there a difference? Aren't those the same color?"

I then quoted one of my favorite movies: "My colors are blush and bashful. One is much deeper than the other."

My husband still thinks I painted the same color twice.
