I frequently paint the walls and ceiling the same color, both in a flat finish.

I do the same Carolyn, except I do eggshell paint.

Benjamin Moore has a ceiling paint finish that is really great.
I would do that on the ceiling and eggshell on the wall.

BM Chantilly Lace is a very light off white color. It would be fine on the ceiling. I prefer their Matte finish but eggshell fine on the walls only.

I also paint my rooms with the same color on the walls and ceilings, using an eggshell finish. I love the look of the eggshell a lot better than a matte paint but that's my personal preference.

Painters like matte because it's easier to touch up. Eggshell/satin is more durable, but you will have to paint the whole wall if you need to touch up. It looks lovely to have the ceiling and walls the same color - just do flat on the ceiling.

That's a very good point Kristin Smith Int.! In fact I just did a repair on a wall this week and repainted with BM regal select. We did not have to repaint the whole wall saving the client $$$. I love BR matte. It really is a lovely , tough finish that is washable. It is not a completely flat finish, more hmmm... velvety I would say. Don't be afraid to use it. Very nice finish indeed.

I like a matte finish on both surfaces and I often paint walls and ceilings the same especially when the color is light.

Thank you SO much everyone for all the feedback!! Pros and Non pros, every comment is so helpful!

I will stick with matte for walls.

The paint specialist who is also a designer said i would save money if i used the same matte for the ceilings. I was hoping I can use a flat lower line of paint from BM for the ceilings (to save money). Of course I will ask the painter this question also but if anyone knows which way is better, please let me know!

I would like to do eggshell for the kitchen, the kitchen is open and connected to the living room, would there be a noticeable difference in paint color?

It will be cheaper to use the same color/product everywhere.

Even tho it's the same color, your painter should charge you a fee to switch product because it requires new, clean rollers, brushes, pans - requires more time and labor to make the change.

You're talking about saving pennies per square to begin with and once you factor in the color change fee, it could actually end up costing you more to use a cheaper grade of paint on the ceiling.

Ohh I understand now, Thanks lori!

I agree with using the same paint for the entire room, including the ceilings. Since I painted both my entryway and living room with the same silvery paint, walls and ceilings, it was more cost effective to buy two gallons of what I wanted and it was the perfect amount of paint, with a little leftover if we need to touch up an area. I did the same thing in my dining room.

Jennjennxx, it sounds as if your paint specialist/ designer has you and your pocketbook in mind. I think you should trust their expert opinion in this matter.
