Final answer:
In Visual Business Director, a green-colored shape denotes that the Source data value is larger than the Reference data value, signifying an increase or positive change.
Step-by-step explanation:
In the Visual Business Director, part of the Pega platform, delta views are used to compare different sets of data, often termed as 'Source data' and 'Reference data'. In these visualizations, colors help users quickly discern differences between these data sets. When observing a green-colored shape in a delta view, it generally indicates that the Source data value is larger than the Reference data value. This suggests that there has been an increase or a positive change in the metric being compared from the Reference to the Source.
