I used to have a rule, 'If there is a black and white image in an opening the whole opening should be black and white!' It was a good rule because it fitted well with my 'Keep it simple' approach to album design. I have however seen some lovely designs from some very talented photographers where they are using the contrast between the black and white image and the colour one to either remind you of colour, or remind you of form. So I have modified my rule. Use colour and black and white together with intent only. Random meaningless mixing creates visual chaos and disturbs the viewing experience. After all rules are made to be broken. Cheers, Johannes
