With a 17 cm/s color map, the end colors on the bar indicate velocities beyond the scale.

• A. End velocities equal to scale
• B. Velocities beyond the scale
• C. Negative velocities
• D. Zero velocity

Answer: (B)

The color map works by mapping a range of velocities to colors from minimum to maximum. The end color on the bar represents the maximum value in that range, and anything that exceeds that maximum is shown with that same end color, signaling overflow beyond the scale. With a 17 cm/s scale, velocities greater than 17 cm/s are displayed using the high-end color, indicating they are beyond the set scale. This is how you can notice when data fall outside the plotted range, while velocities well within the range map to intermediate colors and zero or negative values map to the colors on the lower end. So the statement is correct because the end colors signify values beyond the scale.
