Actually, I'm kinda curious how did you guys tell your contractor on what colour to paint on which wall?
To avoid mistakes and confusion, I've sent my contractor the following few pics, plotted out which part and which colour that I want (based on nippon paint colours brochure) . My contractor said he was amazed to see so many polka dots when he opened up the files....guess I'm the first ever client of his doing this...     

The first layer of paint was done and I'm kinda satisfied with the chosen colours accept the living room and family hall which has been painted in 'hush white'. The 'hush white' colour is too yellowish/creamy to my liking. It makes the room looks smaller and the walls were looked like those already painted for more than 10 years...
I failed to convince myself accepting the colours so I have to tell the contractor to re-paint it to another brighter colour (orchid white). I think I better change it now since it is just painted the 1st layer, rather than regretting for many years to come living in it...
