Monochrome Spectrum

As promised here's a photo of the spectrum of little monochromatic books I made. The purple one I made a few weeks ago, and the rest I just finished yesterday. I intended to post individual pictures of them all, too, but the light wasn't really good enough for photos today.

I was also going to post some pictures of a prototype book I put together today, but again, bad light. Plus, I think I want to wait until I actually have one ready to sell and listed in my Etsy shop. And for that, I need to order some brass screw posts.
