Why Are Some Values in Cube in a Blue Font?

The blue font signifies any data at the lowest level cross-sections which are modifiable.

For instance, Budget and Forecast values at the leaf (lowest) level are publishable and appear in blue font.

As shown below, the values in the blue font for "Subscription Revenue," "Ad Revenue," and "Product Revenue" are publishable since they are forecasts at the leaf level.

The "Revenue" and "Income" values appear in black font as they are parent dimensions and are not publishable.
