Which company developed the visible or color contrast penetrant method?

Explanation:
The visible or color-contrast penetrant method was developed by Magnaflux. This approach uses a colored penetrant that seeps into surface-breaking flaws, followed by removing excess penetrant and applying a developer so the trapped dye oozes out and creates a clearly visible indication under white light. Magnaflux, a pioneer in NDT materials and equipment, introduced and popularized this color-contrast technique, making it the standard visible penetrant method in many industries. The other names are notable in the field, but Magnaflux is the company most closely associated with developing this particular method.
