personally I prefer choosing my own furnishing to match the theme of the flat. ID basically is to help, design, color matching and give ideas/advice... Nowadays lightings are very modern. unlike older days.. With all the basic design of downlights... Led lights and sophiscated crystal lightings nuthing will go wrong. All need to do is to let the ID knows that colors has been choosen for your furnitures and lightings.. Too much of people tagging along shopping and giving advice mights end up complicated and delimma. Overall the house is yours not the ID. just my point of view
