1.The color among different batches may be slightly different due to tolerances in the production process.  2.The color difference is literally unavoidable due to different product photography lightingand rendering technology. Even the screen resolution and the color depth of your screen will affect how you see the color of the pictures. We have tried our best to reduce color differences between displayed images and real umbrellas. But please take the images for reference only. The pantone color codes are available on the fabric tab of each Bluu patio umbrella page for reference.
