Anodized aluminium surface (texture)

[mokusbajusz]

Hello,

I'm new here and need help from Xara users more experienced than me.
English is not my native language, so forgive my mistakes and try to find out what I wish to say...

I work on templates for my website and forum, and I'd like to make images (logos, backgrounds, ranks, etc.).
I'd like to use anodized aluminium surface (is texture the right terminology here?) in many different colours like gold, silver, black, grey, red, yellow.

Their's structure would look similar to this:


I've searched this forum for aluminium sheet metal surface but didn't find what I'm looking for.
Does any of you have an idea of what is the best (i.e. easiest) way to achive the above look with XE4?
Is there a texture or Live Effect included in Xara I could use? If so, which one? If not, what other methods shall I try?

Thank you for hints in advance.

Oh, and happy new year
