I would also like this option. Right now, colours can be applied to png files, but not logos, but png files don't show up in the print file. My products are posters and have several layers (ranging from 38 to 117 layers). I would like to give the option of 12 colours for each layer that the customer wants to display. In order for a customer to apply a colour to a logo layer, I would have to upload each layer as the 12 colours. So, for example, for the product with 117 layers, I would need to upload 117x12 files. And then, in order to display only the layers they select, I would need to do conditional programming for all other layers (e.g., if they choose layer 1 as red, I would need to apply the "do not show" conditional programming to 1,403 other layers. And I would need to set that up in the back end for every single coloured option; which would lead to 1,404x1,403 conditional logic lines, which would not be possible).

For this reason, I can't use Kickflip.
