@ Fergus: well, it's a bit your fault Fergus. You asked both Bob and me and then it was not possible to understand that you were not speaking to both of us. About the color, I first understood that you wanted pieces on a blue background, so did Bob, then that you wanted blue pieces on a black background. If you prefer white pieces on a black background it is not a problem at all.
Actually, there is something VERY simple to do, a piece of cake for you.

Actually, there is something VERY simple to do, a piece of cake for you. You go to:
https://www.thingiverse.com/kazo65/designs
There you can download the .stl of the piece you would like.
Then you open that .stl with:
https://3dviewer.net/
And you can have a snapshot of that piece with the color you like, the background you like, the orientation you like, the size you like, etc.
If you can't do that and need help, please tell me exactly which piece/color/background you would like, I will make it for you.
