Not a very good option for indian family lifestyle at least. But again its a subjective matter, depends on the choices. White is best when it is a Pure 'Minimal' Design. British Architect John Pawson is one i find best in my knowledge till now who is doing minimal architecture in its purest form. And i don't see any in india who is doing such work.

Yes, as Cornerstone says, please don't redo the water-proofing if it has already been done once. Tiles are a far better option than decking with composed fibre-wood. No matter how hardy the latter material is, it is going to be a muddy and wet area, so please go with a good anti skid ceramic tile. Check on the final use with the manufacturer- that it is going to be laid on the terrace and exposed to sun. Use at least 3 mm spacers to allow for some expansion over a period of time. Also leaves enough space to insert waterproofing epoxy and secure the tiles
