P.S ...re-painting is not an option. The land lord won't let me :(

Wow my first place had that color in LR and Bedroom. I can relate lol How long will you be there? If you are buying furniture try and think longer term. If you are not going to be there a few years then get neutral furniture that could work in another home and use accent throws or pillows to tie it together. You vould try a floral fabric as a starting point. Or better yet area rugs with a pattern that has some green in it. Get some landscape prints or do black adn white photos on wall to give the eye somewhere else to look. That way the only things that match the walls and rugs are not so expenisve area rugs and pillows. Best of luck

Pick up large inexpensive carpet remnants or area rugs in a color that will work with the walls. The green carpet is much harder to work with than the walls.

great ideas!!! thank you soooooo much!!

Unless you're planning on staying here for MANY years, love yellow and green on their own merits, or have money coming out your ears to replace it all when you move, don't buy new furniture based on this color scheme.

You don't say anything about what your decor taste is, so you may gag at this, but I can actually see this yellow-green "issue" working pretty decently with a casual cottagey/beachy kind of feeling - white-painted case goods (yard sale stuff with a can of white spray paint, you know?), airy white cotton window treatments, some navy blue touches and even a tiny, tiny bit of red... If you have existing seating furniture and can deal with slipcovers (I think they're love 'em or hate 'em things, because I absolutely loathe them and some folks here think they're the greatest thing since sliced bread) those would probably be your best route. Surefit has a slipcover in a blue-and-white ticking stripe that would work well and is pretty inexpensive; complement it with a couple of throw pillows in a print incorporating white, yellow, greens, and blues. A braided rug in blues and greens could anchor the seating area - there are special pads that will hold an area rug on top of most carpets. (If the carpet is very plush with a thick pad underneath, it doesn't work so well, everything sinks!)

I must be more of a rebel than my Catholic school upbringing usually takes me but I say PAINT ANYWAY. I just can't imagine a landlord snickering about improvements made when you'll move out 1+ years from now... Leave some leftover paint for touch-ups for the landlord/next tenet.

I'm like whenicit..........I'd paint. At the worst you'd have to paint it yellow again when you leave.

Did you ask the landlord about painting based on you buying the paint?

I agree -- offer to purchase the paint and do the work in a nice neutral. Then, look into some large inexpensive area rugs - check Craigslist or Big Lots to cover up the green carpet.

You don't say if you own furniture or not; that makes a huge difference in the type of advice I would offer.

Maybe y'all have just had way nicer landlords than I have, but doing something as major as repainting expressly against the landlord's stated wishes would have been a violation of lease terms that would have at the very least lost me my security deposit (had that happen, BTW, learned my lesson) and can be justification for the landlord terminating the lease. Read the lease, there's likely something like "tenant shall make no alterations to premises without written consent from landlord".

However, it did occur to me late last night, as these things often do, that if it's within budget the OP should look into the EasyChange peel-off wallpaper from Sherwin-Williams. I don't know a whole lot about it but they do guarantee it will not damage the walls. Worth checking out, at least.

I am a bit of a rebel.. but painting the walls when the landlord expressly said "no" is not advised. I would ask twice though.. maybe the second time with a color swatch in hand. I doubt the landlord would allow a floor covering change though and that seems to be the biggest issue. I would not use removeable wallpaper or anything expensive-- put that money into the elements you will keep-- or towards a deposit for your own home.

What's your style, swetiepi? There are some really cool pillows and accessories in bright yellows and greens-- can you play with the colors rather than trying to mask them? The last few Pottery Barn catalogs have featured light colored fabrics with some great green and yellow pillows and draperies. They are a bit bold but bright, fresh and fun. A navy accent would help tone the colors down--red would make them pop.

If you are a bit more traditional, a plaid fabric with your green in it should work well. It's really dependent on your style.

I would tend towards darker furniture to stand up to the colors but I'd imagine you could make any wood work for you.

Oh dear, I so feel for you. My apartment is yellow throughout. Every stinkin room yellow. I am not allowed to paint either. Thankfully I have hardwood floors. I would suggest getting large neutral-colored carpets - you can get bound carpets at Walmart sometimes that are 9 X 12. Cover up the floor as much as possible, and the yellow will be easier to work with.

What is it with landlords wanting to preserve their own color scheme?!?

Oh, no! Definitely don't repaint if the landlord has expressly advised you not to! I do like the idea of picking up a large rug or two that will work with the yellow walls.

We're renting our old house while we're waiting out the real estate recession, which I had painted in a very light, light beige. The renters wanted to paint a room red. I said NO, and I would definitely have kicked them out and kept the deposit to cover the cost of repainting if they went ahead and did it against the express terms or our lease.

I feel for you on the yellow-green, but strongly recommend against painting in violation of your lease. There are a lot of very nice rugs that are room sized. I would think it would be easier to work with the yellow on the walls than the green carpet. What about a nice banded jute rug that is room sized?

I always painted my rental places too. Maybe try asking again - promise to repaint in the yellow or another neutral of their choice - at your expense.

Landlords are usually worried about being left with some godawful purple wall colour or something when the tenant moves out. If you choose a reasonably neutral colour they probably won't care in the long run.

And if they do -- still weigh the cost of losing your damage deposit against the cost of buying new rugs etc to accommodate colours you don't even like! :-)

Wow, I feel for ya! That color combination would make me crazy!

I'm a landlord myself and the ONLY way I would allow a tenant to repaint is if they offered to have it professionally painted whatever color they'd like and then REPAINTED the original color upon moveout (again by a professional). All our apts are painted a neutral beige color, but the reasons landlords don't allow tenants to paint is #1 they're worried about tenants doing a shoddy job (not trimming out, getting paint on flooring/carpet, etc...) and #2 being left with a color that can't be touched up upon moveout. We paint all our apts in the same color so that way, when we go to prepare the apt for the new tenant we can just touch up certain spots that need repainted vs repainting the entire apt.

Good luck - maybe find some funky rugs & artwork to jazz up the space?

First of all, what exactly is the problem? You don't like lemon yellow or you don't like the green carpet or you just don't know how to pull it together?
If you don't like the yellow color, see if you can repaint. It doesn't hurt to ask. If the landlord says no, then don't paint! Consider the yellow color a neutral background and use pictures around the room. Pull your color scheme from the green carpet and decorate around that color.
If you don't like the green carpent, purchase an accent rug to go over it and play up the yellow.
If you just don't know how to pull it together, go to the bookstore and spend an afternoon browsing the color books. Yellow and green scheme lends itself to a lovely garden, floral, outdoorsy, cottage casual, or country look. Crisp white curtains and some green plants will go a long way to help bring tht room together. Good luck and give us an update.

I second the suggestions about carpet already made: remnants, sisal, whatever will cover up that green. (how green is "Christmas"? Hunter green? astroturf green?)

As for the walls, have you gone to the landlord with a chip or two? Both Lowe's and Sherwin Williams have brochures with all their whites and off-whites. Select a few you think you could live with, and then ask the landlord about this.

If s/he says no, both johnmari on this forum and ApartmentTherapy (a great design blog) have lately posted directions about how to "upholster" walls using just muslin fabric and sizing starch. Easy to take down when you move, and leaves no marks on the walls. You'd still have the carpeting to contend with, but at least your walls would be off-white!

I think carpet remnants over carpet would be awfully squishy underfoot, and difficult to vacuum.

I don't have any carpeting in my home now, but in previous homes, I've always had rugs on top of carpet and I didn't find it too squishy or difficult to vacuum.
