They used a tinted primer! Here are the actual paint colors. We like the color in the living room (it's the same as the hall and bedrooms), but that kitchen/bath yellow is awfully bright! I picked it, so I guess I'll live with it for awhile. It might look better once the cabinets are in. The photo below shows the master bath. The cabinets in there will be very dark, so the yellow might look great, who knows? I can always re-paint later!
I wish someone would come back and work on the siding. It's not been touched in 2 weeks! (It's not a sub--our actual builder's crew is doing the siding.) So, siding's still about 25% done.
