lighting and colour for my film

I a planning to divide the mood in two parts. The first part which is light and warm. I am planning to bring bright colour and warm lights with the use of tungsten light.

As seen in above stills from the films. We can notice the bright colour which bring our eyes into the character and bring comfort to eyes and the warm colour of tungsten lights... Which enhance the feeling of love.

For the second part of the films. I am planning to use blue light and light colour to highlight the loneliness of the characters. 

As we can see the use of blue colour and very unsaturated colours bring the loneliness and the sadness of the characters.
