Can the painters add white to lighten the colors & just repaint what they've done already? I'm sure they have dealt with such problems before - it's really difficult to know what colors will look like on large spaces, especially when the walls reflect on each other, which deepens the color.

Actually they have to put a second coat on the kitchen tomorrow morning. I wonder if I could lighten that color and have the second coat look ok? It's the most "tuscan" of all the colors, and I think the one that is bugging me most...

I would take the paint back to the store and ask them if they can lighten it for you.

You could have them stop, and you could choose another color. I had to do that in my kitchen, the green I selected was a bright granny apple green (nothing like what I saw), so I went with a more muted color on the same color card.

Talk to your painters and see what they can do.....asap. Better to make any changes now before they go any further or leave the house.

I can tell you it is a shock when a dark color goes on the wall for the first time. My guess is it won't be so drastic once it's all done and the furnishings are back in place.
You did paint a large part of your wall before deciding on the color, right??

I'm not sure how to exactly de-tuscanize it, but I just want to say that I I doesn't make u happy, speak up now. I'm telling u from experience. I spent weeks testing samples and just yesterday and today we had the entire house painted. We did the morning Rm SW humble gold and both the fam Rm and kitchen blonde. I hated it. Looked so super yellow and glowing all over. I tried to love it, thought I'd love it overnight, but this morning I knew I had to hav it changed while the painters were still here. My DH was not too happy w/ me, but I didnt care. I knew this would bother me, so I asked them to change the kitchen color to the lighter neutral color of the foyer (believable buff). I can't even tell u what a difference it made. And even my dh agrees. He said he's happy that I'm happy :) I love the look of all the colors now. So my point is, now is a good time to do something about it whatever that may be! Good luck!

It is not the responsibility of the painter to get the color right, they apply the paint you choose. Take it back to the store, mix up a qt and get it right before moving on. Do not ask the painters to "add some white" to get it right. The store does this not the painters, not anymore.Back in the old days, yes.

What style are you after? Perhaps Tuscan is the only style you can connect with the paint chosen. You might look at fabrics with the style you are wanting, the colors loved and consider which dark works. I love arts/crafts and the dark teal with other colors used or rustic. So my heart says this is what they are style wise.
