The Venn View superimposes defined data subsets and displays record/row counts for each subset and all intersections. The colouring used for each data subset depends on which file-wide colour pallette is selected from Style > Data Colours > Continuous (each option selected can also be further custom-edited to define starting, middle and end colours to be used to generate a custom pallette for the file).

The value assigned to each subset to determine which colour is used in the Venn View is the record count within each data subset, relative to the record count in the other defined data subsets being visualised.
