How can color contrast aid VT on painted surfaces?

Explanation:
Color contrast in VT is about making indications stand out against the surrounding surface so the eye can detect edges and differences more easily. When you use colors that contrast between a defect and the coating or substrate, the visible differences create sharper boundaries and improve the ability to see the indication. This helps reveal flaws like cracks, blisters, or delaminations that might blend into a uniform color. A uniform color provides less delineation, making subtle flaws harder to spot, and color contrast by itself does not damage coatings.
