Blue-grey focus
Using the MBL blue-grey colour, images could be blurred and colourised. Only the main subject area of the image is clear, sharp and in focus, suggestive of the targeted approach MBL takes in streamlining client logistics, distribution and compliance.
So although images may be of very different subjects, colours and environments, the Photoshop treatment across all images would give them a consistent brand identity.
This approach could also be adapted to banner images.
