Well for windows and doors you'd use gloss or satin finish paint in white and it shouldn't really be different to your white wall paint in colour , if you used the same shade of white from the same company.

Is there a reason you have those colors on the walls? Without pics we are in the dark. What exactly is your style ?

I am thinking of using pastel light green colour for walls of our dining area. Since our living room is continuous with dining area, what should be colour for living room as I am not too sure if same colour across will look good. I am thinking of using olive green or rose gold dining chairs and warm white light on ceiling. Size Living room..10*9 Dining+lounge 18*8 ft
