I am assuming you haven't finalised your wall colours and colours of any other fixed elements. In case you have finalised your color scheme you would need to see which of these colours blend well or complement with that scheme. Assuming none of this info is available, then you could look at the neutrals which go with all colours. The white tile and the 2 colours at the end would be preferable. If you want color on the floor as well as drama, you can choose from the 2nd options from both sides or even the 1st from left.

antislip and easy maintainance tiles for exterior is the key. choose any shade, colour, size. must not have deep textures as that's gonna be tough later in use. do consider slope and drainage appropriately as terrace may lead to water proofing issues in future. make sure skirting is everywhere and corners with top part of the balcony wall is tiled properly. thanks shradha shah beescheese design

Creative Creaturz, 1- There is no such thing as a floor tiles trend that some one starts and everyone copies. Often designers choose their own pick based on design in mind and often the taste of the clients. If you can afford go with a professional for selection. Wholesellers don't have a lot of display and time you may want to go to other brand stores/galleries for varieties. Yes , you are right builder/contractors often choose uni colored tiles for convenience, lesser costs, standardised look and larger floor feel. Multi colored tiles look better in bigger areas unless your style is eclectic. Neutrals are always better to change themes. Gels with multiple designs. Bigger Tiles Merits, Looks cleaner and stylish, lesser grouts, much easier to clean. Demerits: Needs expert installation, costlier. Thanks, Nitin Cornerstone Designs, Bangalore.
