🔍 Key Concepts

• Dye penetrant testing shows flaws by using a contrasting color between the indication and the background. • Universal color contrast-type penetrants are designed for visible inspection under white light, not UV light. • Think about which color combination would make a fine crack or defect easiest to see on a weld surface.

💭 Think About

• Which part in this system usually provides the background color—the developer or the penetrant itself? • In a visible contrast dye penetrant system, does the indication (defect) show as the color of the penetrant or the developer? • Which of the color combinations listed would give the strongest contrast for the human eye when looking for small, fine indications on steel welds?

✅ Before You Answer

• Identify which option pairs a strong primary color indication with a light, contrasting background. • Eliminate any options that would make small linear cracks hard to see under normal white light. • Recall that in standard visible dye penetrant testing the developer is usually light-colored, and the penetrant is typically a strong contrasting color.
