Light colour will make the room 'look' more spacious.
Romantic colour very subjective ler. But most of the people think pink and purple look romantic.

Good question...this is depend on individual with what he / she prefer colour, that the reason you better DIY using those tool, also it is free hence the consultant only give advised base on what your prefer else he/ she will choice from you.
Example: I ask my Kids what the prefer, than I informed the consultant, the he do the matching including the code, but at that end I select more light colour from the list.

ALternative your could got for ID too, which will be charging you each design.
From how you respond, I guess you already have idea what your preference rights?

Feature wall is the first wall u see once u enter the hall/room - it's either right or left (depending on which side your door opens first). Do not use the end of the hall eg at the sliding door/balcony area. If for bedroom, the feature wall will be at the head of your bed. Only use your favourite colour at the feature wall, the rest of the walls should be neutral (either warm or cool) . Warm neutral is advisable for living/dining and cool neutral suitable for bedroom.
