Derby County Jersey (Away) 21 22 Season - Blue

If you're asking about a blue away kit, here's a general idea of what it might look like based on typical football jersey designs, although the specifics could vary quite a lot:

The jersey would be predominantly blue, the exact shade of which could vary—everything from navy to light sky blue has been used for football away kits. The jersey might include the Derby County crest on the left chest (from the wearer's perspective), and the kit manufacturer's logo on the right. The team's sponsor's logo would likely be prominently featured in the center of the jersey.

Further design elements could include contrasting colors for the jersey's trim, such as on the collar or sleeves, or patterns or textures subtly woven into the fabric of the shirt.

Since the design, color, and style of football kits can change every season, for the most accurate description of Derby County's current blue away kit, I recommend checking the latest images on the Derby County F.C. official website or their official social media channels.
