Rubber materials, especially our Polyurethanes, can vary in shades due to quite a few factors. This is very normal and, if the product is used within its suggested shelf life, it is expected to cure and behave as it usually does (with the only difference being the color). Because of the many factors that play into the color of the material, we cannot guarantee that the rubber or plastic you receive will be the exact same color every time.
As an example, here is a photo of cured samples from different batches of EasyFlo Clear, a polyurethane plastic.
