I love dark shades but from my experience oil stains on a dark shaded cabinets in kitchen specifically are more prominent.

Not necessary to use only paint for the change. There are different applications like wall papers, textured particle board, wooden panels etc. It actually depends on who is using the room. For the changed looks, go for wall paper on one wall and color selection as per the age of the user.

If y don't want falseceeling you have to plan before roof concrete where you have to plan lights

Suraj, If you have access to the room that you shared earlier you can try seeing the flicker effect at night time with both lights and fan being on. If the lamp has a 360 degree light spread it will cast the fans shadow on the ceiling and when the fan is turned on it causes a flikr effect. I personally find it a distraction and at the same time many would not even notice it. Take the pick based on your usage. Wall mounted fans and recessed fans can also be explored.
