Tableau-Desktop-Found Understanding Tableau Concepts Practice Question
A logistics analyst wants to highlight orders whose shipping cost exceeds a fixed threshold of 500. The analyst creates a calculated field returning a Boolean result and drags it onto the Color shelf, but the resulting legend shows only 'True' and 'False' labels with generic colors. The analyst needs a two-color scheme where qualifying orders are red and all others are gray. Which approach best accomplishes this in Tableau Desktop?
⚠ Common exam trap
The trap here is reaching for a filter to distinguish qualifying records, when filters remove data instead of recoloring it.

Correct answer & explanation
✓
Right-click the Boolean field on Color and select 'Edit Colors', then assign red to True and gray to False.
Placing a discrete Boolean field on the Color shelf generates a two-member legend. Using 'Edit Colors' on that field allows explicit assignment of red to True and gray to False, giving the exact two-color encoding requested. This keeps all orders visible while visually distinguishing those above the threshold, and it avoids altering the calculation or splitting the analysis across multiple worksheets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Drag the Boolean field to the Filters shelf and set it to True, which automatically colors matching marks red.
Why it's wrong here
Filtering to True removes non-qualifying orders from the view entirely instead of coloring them gray. Filters control which rows appear, not mark color. The analyst wants all orders visible with differentiated colors, so filtering would hide the comparison the analyst needs. Color assignment requires the field on the Color shelf and manual palette configuration.
- ✗
Create a separate worksheet for qualifying orders and another for the rest, then place both in a dashboard.
Why it's wrong here
Splitting the data across two worksheets complicates the view and does not color marks within a single visual. It also duplicates axes and filters, making comparison harder. The analyst simply needs two colors on one view, which is achievable directly through the discrete color legend. A dashboard adds unnecessary complexity for a straightforward color requirement.
- ✓
Right-click the Boolean field on Color and select 'Edit Colors', then assign red to True and gray to False.
Why this is correct
A discrete Boolean field placed on Color creates a two-member legend that can be recolored directly. Opening 'Edit Colors' lets the analyst map True to red and False to gray, producing the exact two-color scheme requested. This is the standard way to control discrete color assignments without changing the underlying calculation or converting the field type.
- ✗
Convert the Boolean field to a continuous measure, then choose the red-gray diverging palette.
Why it's wrong here
Converting a Boolean to a continuous measure is not a supported conversion and would not yield two clean categories. Continuous color palettes interpolate across a numeric range, producing gradients rather than exactly two colors. The requested outcome is a strict two-color split, which is a discrete color mapping, not a continuous range.
