The black and white was really just a sign of the times! I did a 2,000 copy print run, as there was no print on demand or digital comics channels yet. Color was just too prohibitive a cost! I honestly didn't mind though as it did fit the story. My intent was also to pull a bit of a Wizard of Oz type trick. I used pure B&W here, but at a certain story point greyscale shading was going to be introduced.

New material in the future will certainly be color, dark & muted of course. There's no technical reasons not to and there remains some readers who simply eschew black and white content (though manga largely broke down that barrier too!)
