Another possibility is a clear surface coating (similar to auto clear coat) was added over the white base. If one was acrylic and the other alkyd, this type of color can result. I have seen everything from a barely noticeable tint to a deep "bottle" green when this is done with architectural and some industrial coatings. And it doesn't also become noticable until the coatings have aged or been exposed to sunlight. JeffW. - This message is from the Pentax-Discuss Mail List.
