We do our best to make sure that the color of the product you receive is as close as possible to what you see in the product listings. There are many factors, however, that may lead to a discrepancy.
The most likely factor is the screen in which you are viewing the listing photos. We use a color calibrated monitor and carefully adjust the color of our product photos in Photoshop to match the actual product. We use a Mac standard gamma of 2.2 which is slightly darker than the typical PC standard gamma of 1.8. If you are very particular about color and want to see the product photos as closely as possible to the way we see them, calibrate your monitor and set the gamma to 2.2.
With that said, colors look differently in different lighting conditions. We correct the white balance of the images for the actual lighting conditions when the photo was taken, so the photo should be very neutral. We can't control the lighting under which you view the product once you receive it, however. If you feel there is a discrepancy, please view the product in direct sunlight (or at least under a daylight bulb 5000 to 6000K.)
To further complicate matters, leather, as a natural material, has natural variations. Things like scars or dense patches will not take the dye as readily as other areas. The base color of leather will vary from hide to hide and even within a single hide. This affects the resulting finished color. When the product is finished, we use our best judgement on the color (as we do with the quality of workmanship in general,) and decide if it is up to our standards before we ship it.
