Thanks so much!
This brings up a really interesting design facet! I hadn't thought of reformatting the cards and map to a 'more white' version for people that can't buy a print-on-demand version. I really want to share this insight with all my friends here in the US who design games that then either have to be shipped overseas at a huge cost, or printed locally.
I did plan to include a final version for publication that was print-and-play friendly (with all cards imposed onto standard paper sizes) but i had not considered the color constraints - that is brilliant. Need to make that common knowledge.
