I cant tell from the image if they are glossy or not. But if they are - they might be Austral Brick Burlesque Chilled Black. If they are not, check at brickwork or austral brick to find something similar to your brick type in the picture, because there are many different bricks similar to the one you have shown.

Emily A permanently roofed al fresco will reduce some summer heat gain (although sitting out there may be uncomfortable) and will do the same for winter. From scanning the comments it appears that you are at a point where you can still may major changes; I cannot recommend strongly enough getting the orientation of your new home right, it will be warmer in winter, cooler in summer and be significantly cheaper (if not free) to run with some appropriately detailed insulation. I do understand the appeal of a floorplan that seems to be all you have aspired too but have seen many a case where people have later regretted those decisions. If you are unsure about the pros and cons of various floorplans then get a design professional (building designer/architect) to give you guidance on an hourly rates basis. good luck

yes to all, we did have the tiles professionally sealed, but sealing is not a cure all in my experience but I'm sure it helps considerable . my wife does buy those hand made goats milk styles soaps etc and I don't imagine there is anything more testing for stone, and yes it does mark. The Grey ( bane of my existence )granite much more so than the beige travertine ) I must admit though, the kids bathroom was almost non existent as one has sensitive skin and uses pump pack. I would also imagine climate, airing/ sunlight, volume of use and the time you have to manage it would also be contributing factors. We are way short on time and they don't get the attention they deserve, so I would suggest asking around, others may manage it better and it not be an issue. If your only doing your bathroom you may consider the risk factor not worth it for the volume, but for me, the advantage of travertine in the rest of the house far out weighs any marking issue in the showers, and wont stop me from using it again. To be honest when we sold the last house I just took to the shower with one of those paint scrapers with the razor in the end and most of it came off and it didn't detract from the look of the house. Sorry i have probably only muddied the waters even more, good luck with it.

You could try asking your question on the dulux Facebook site. They often have colour consultants offer suggestions as to what colours might give a similar result to pictures people have posted. Ultimately though, you should probably choose your timber and stone cladding first and then choose paint colours to work in with those tones.
