How can I separate color scheme in my mobile home?

Maybe put a 2x4 board across the ceiling, stained or painted.

Where the living room stops, begin your other color there. I would end the living room color where the bar begins. Make sure your line wall is straight. Hang pictures or collectibles on this line and the change of color will not be that noticeable. If the ceiling is involved, paint the same color ceiling throughout, like beige or off-white. A beam or board as suggested above, is a good idea. The choice is yours, whatever you like. Anything goes nowadays.

since you can see each room from the other, the colors need to be compatible , but complementary if you truly want a DIFFERENT color go with a 'complement' color -- if you want something less 'different', go with something closer to one or the other -- a 'shade' of one or the other. -- a COMPLEMENT color is one directly across from the other on a color wheel --- a paint store can help you; In a smaller area, to make it look larger, I'd go with a SHADE of the base color and use the COMPLEMENT colors for accessories .. curtains, rugs, pillows, etc.

I am assuming you want to paint different colors? If so, you can separate them but keep them compatible.

I would suggest at the point where the bar meets the living room, you make some sort of eye distracting divider. This could be a simple like a half or boxed column...the kind that fits close to the wall. It could be made from a dressed up 2x4.

Then repeat the same effect on the other side. These would not be hard to construct...a little molding and calking and paint.

This would be pretty with, say a medium shade in the LR and a lighter shade in the kitchen. If they are of totally different color schemes, tie the two together with accent pieces.

For example, those blue chairs in the living room can be tied into the gold in the kitchen by adding a blue vase near the stove to hold your stirring spoons...and a gold throw or some gold pillows in the living room.

Just wonder why you want the two areas different wall colors?? JMO, one color will expand the area, maybe a tone up or down or a mini accent "wall"...if you paint the bar furniture a beautiful contrasting (or not) color it will make the eye see that as a partition ....change colors with accents...go have fun...

Keeping the colors similar or at least complimentary will make your space appear larger. Keep the flooring the same. But use an area rug in the living room section. Anytime you have a home where the other rooms are visible the rooms should be complimentary to each other..

Hi Linda. If you carry a base color through both areas, it will serve as a “blend” if you will. Then you can add your colors or pops of color to each room. EX: if you ain’t living room blue and paint your kitchen yellow, it will clash badly. But if you paint a base, then add your colors to each room, it will help blend and separate at the same time. I would not recommend doing the 2 separate colors.

paint the kitchen ceiling the same color as the living room walls. Then paint the living room ceiling the same color as the kitchen walls. Vola! Easy as that. It looks beautiful And solves your problem. No wood, nails, glue, pictures...etc. Just paint.
