Why did the british officials put everything in black and white?

British officials often used black and white imagery, such as photographs and printed materials, to maintain clarity and a sense of formality in communication. The lack of color ensured that the focus remained on the content rather than distractions, emphasizing the seriousness of the message being conveyed. Additionally, the use of black and white was practical, given the limitations of printing technologies at the time and the need for cost-effective dissemination of information.
