Hello Peter,
Right now You can not change the colour, However it can be customised the way you want. Please contact our Sales team via Contact us -> Request a Quote form, We'll look into it.
Similar to pre-set T-shirts, is it possible to select different design backgrounds for one product. I have pens which are all the same style but have different colors. I'd like the design tool to be able to switch colors for the one product.
