Your home is grey with a bit of dark brown. Grey in the landscape is the best color for structural elements; concrete, patina of UV'ed wood. To insist on dark brown mulch will drive you crazy. Don't mess with dyed anything.
A good mulch will be decomposed...this will feed your soil organisms. Dyed non decomposed mulch will cause the life in your soil to go dormant to allow the decomposers to decompose the organic matter. Decomposed organic matter is all that the soil organisms are able to eat and use for energy.
If your mulch is decomposed it will start to disappear because it is being eaten by soil organisms, taken backed down into the soil to be pooped out and mixed into your soil without any effort on your part. Good mulch will need replacing.
My favorite and the only mulch I will use for ornamental plant beds is; are you ready for this?...human poop mixed with sawdust and completely decomposed. Dark taupe, texture like coffee and let me tell you your soil and plants will love this mulch. Problem is, I have found this mulch is not that available. I will not use bark or non decomposed mulch. That is counter productive. This stuff is Federally managed tested 5X, but it is the only mulch where you are able to get a printed copy of the chemistry! Smells wonderful. Texture to die for...no weed seeds...no pesticide residues, just a bit high in heavy metals so we don't use it for vegetable gardens. Heck most tap water has higher heavy metals but still...
Check with your city's sewer utility department whether they offer this product or who they sell this stuff to so that it is available to the public. Yes, you will have to replace yearly. A couple of inches, no weeds, your plants will go nuts! Your soil will be so vigorous and healthy you probably won't have to worry about much extra fertilization for your plants. I never worry about weeds. Where I live now I am quite unhappy that our sewer and water services do not make this mulch. Other mulches that are commercially made are very suspect. Made from homeowner's 'clean green' or grass clippings and other landscape debris, these mulches even after decomposed will be full of pesticide residue to the point you won't be able to grow a petunia.
Keep the colors of your structural/architectural elements light dove grey. This is the advice of a seasoned landscape architect. This provides a 'frame' for your plants. Adding odd colors makes a landscape chaotic.
Whatever you do, do not use plastic or 'weed fabric' ...please. Do not use. That is the worst practice that somehow got started. Doesn't work, inhibits the soil organisms from getting fed, blocks water by ruining drainage, is loved by slugs, snails, pillbugs and earwigs. I have ripped out so much of this stuff as the first thing I insist to do before any landscaping. Seriously. Stone or gravel does not 'feed' the soil. Without a healthy soil with lots of fed and multiplying macro/micro soil organisms, forget about healthy vigorous plant material. Weeds are the least of all problems in a garden. 2" of mulch will stop weed seeds from germinating, kills established weeds. Weeds are just not that big of a deal. 'Weed' fabric is not made for 'weeds'. It was made to create a barrier between soil and installed gravel so that the gravel doesn't sink and the fines of the soil come up and the gravel gets lost and weed seeds that blow in or pooped out by birds have a super medium in which to grow. Someone thought they could label this stuff 'weed fabric' but anyone who understands soils, plants, gardening knows that this weed fabric is a hoax. 2" of mulch will smother established weeds and stop weed seeds from germinating. Putting down a layer of plastic that stops water and organic matter from becoming a natural part of the soil is insane.
Stay with grey...definitely goes with this beautiful home. Check out your sewer and water facility to see if this mulch is available. I am so serious. Hate to say this stuff, but I designed, installed and managed 100K projects all of the time. I would not use bark. I had to rip up the plastic. If they insisted on keeping that stuff I would simply tell them to find someone else. I would never put my name or reputation on a landscape with plastic, bark mulch. Hey, I spent some time educating my clients. Happy clients. Beautiful landscapes...healthy landscapes.
Oh and the rubber mulch that Carlton is talking about is an incredible fire hazard. Installing many many kid's play areas, I had to explain that one little ciggy butt would cause this stuff to go up in flames. Would not use rubber mulch period. Sorry Carlton!
