We had thought that room colors will be relatively easy to choose, since we only wanted white walls. However, we didn't expect there will be so many different variants of white! Also, we were deciding between Nippon and Dulux, since these two are the more popular and trusted brands. Price-wise, Nippon seems to be more expensive than Dulux. Of course, it also depends on which product range of the selected brand you go for. It is VERY important to specify the range of paint in your quotation. If you just specify Nippon, the contractor may just use a cheaper range of Nippon paint e.g. Vinilex 5000. You also need to check how many colors they are limiting you to for your entire flat (sometimes only 3 and you have to top up for more paint), and how many coats of paint you are paying for (minimum should be 2, some contractors do 3). If you are hacking walls, consider getting your contractor to put a layer of wall sealer over the affected walls before painting over them. Eventually, we settled for Nippon Odour-less EasyWash. Nippon has 10 different variants of white. We picked Sail White for our living room and study room, Orchid White for our wardrobe room and Lily White for our master bedroom. Sail White looks good, just like the white we imagined . However, Orchid White and Lily White do not look like what we see in the catalog ! The differences are more dramatic in real life when you are looking at an entire room painted with the color compared to just a small box in a catalog. Orchid White in wardrobe room looks more pinkish than expected: All in all, we were fine with how the painting turned out. But if you think you are very particular about the colors in your rooms and want them to be as perfectly as you imagined, it would be good to drop by on actual flats with the same color you are planning to use. Ask around on your project Facebook page if there is one, or consult your contractor . You could also check out your neighbour's flats when they are doing their renovation. However, do be polite and ask first before going in uninvited!
