The "Colour" parameter is a quad-array: [R, G, B, Alpha], or can be a named colour, see [OpenSCAD_User_Manual](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#color).
For speed sheets should be modelled in 2D by subtracting holes from 2D templates made by ```sheet_2D()``` and then extruded to 3D with ```render_2D_sheet()```.
Note that modules that drill holes will return a 2D object if ```h``` is set to 0 to facilitate this.
For speed sheets should be modelled in 2D by subtracting holes from 2D templates made by `sheet_2D()` and then extruded to 3D with `render_2D_sheet()`.
Note that modules that drill holes will return a 2D object if `h` is set to 0 to facilitate this.
If 3D features are needed, for example countersinks, then sheets can be modelled in 3D using `sheet()` and then coloured with `render_sheet()`.
When woven sheets (e.g. carbon fibre) are rendered it is necessary to specify the dimensions again to `render_sheet()` or `render_2D_sheet()`.
