Discussion about filming in black & white

We've been discussing that as part of our opening title sequence there will be a section that is shown in black and white. But we all have mixed opinions on this matter because the section that would be in black and white takes part in the future. The issue is that a scene that takes part later on in the film, would firstly be shown directly after the opening title sequence or as part of it and then be show later on in the film when the event would actually take place in the chronological order. However we need to make the final decision as to whether it is filmed in black and white or in colour. I have done some research on the internet and found some films that at some point will change from colour to black and white or vice versa.

For instance, the film 'Schindler's List' features the opening title sequence in colour and then gradually changes until black and white for the rest of the film (except when we see the 'girl in the red coat') until the end of the film where it eventually changes back to colour for the end credits sequence scene.






The film ' Kill Bill: Volume 1' features its opening scene and opening title sequence in black and white. Afterwards the film changes to colour and at various points changes back to black & white with an additional scene in an animatic format. One possible reason that the opening scene is in black and white is because the film has many homages to old films and this is just one of them. So basically the idea of having our opening title sequence in black & white is a homage as well and this time to the film noir genre.
