Abstract
Standardized colours and codes are essential for ensuring consistency in geological mapping. Currently, the Geological Survey of Pakistan lacks a unified theme for assigning colours and formation codes. This paper details the process and results of an initiative aimed at standardizing these codes and colours. We utilised the USGS colour scheme as a foundation to develop a tailored colour chart for the Geological Survey of Pakistan. It was very challenging to allocate a unique colour to each formation while ensuring that these colours are easily distinguishable across different maps. Our findings indicate that the adoption of these standardized codes and colours significantly improves the clarity of geological maps, enhances understanding among researchers, and fosters better collaboration among stakeholders. This standardized scheme provides a uniform reference system, thereby increasing the usability of geological maps and supporting more accurate and efficient geological analysis and communication.
