What colour fabric is used in your picture of the ottoman bases?

Hi, I have been looking at your ottoman bases and have looked at your different fabrics available. However, I wanted to know what fabrics are used in the pictures on your website - I'm looking for a silver/grey. Thought at first that 'Flint Chennile' would fit the bill, but when I enlarge the fabric sample, it looks more of a blue(ish) colour?
