Hi CRISTIAN - Thank you for your review. I'm sorry to hear that the samples you purchased didn't turn out as expected. The color swatches online may vary from the actual color you apply to your project, so it's best to check out the paper swatch and pick up an 8 oz. sample for the most accurate color representation. You can also check your color samples for accuracy by comparing the paper swatches to the dried paint dab on the lid of each sample jar. For further assistance with this, please feel free to reach out to us directly. We'd be happy to help. - Sara
