Some of the characters are able to move from our reality to this new, alternate reality. If this sounds just a little like a Philip K. Dick-type premise (a la <em>The Man in the High Castle<\/em>, etc.) you&#8217;re not too far off base&#8211;and you&#8217;ve nailed down the book&#8217;s appeal to me: I don&#8217;t read a lot of SF, but when I do, the stuff I enjoy tends to be more cerebral stuff along these lines.\u00a0 Ultimately, we abandoned the idea of putting this together, but in hashing out how I would handle some of the more challenging parts of such an adaptation, it occurred to me that the two overlapping realities in this book might be represented visually with things like transparent overlays and\/or pages that show through die cuts. Imagine, for example, lifting a page of panels printed on a transparency depicting the alternate history reality from the book and seeing beneath a corresponding &#8220;reveal&#8221; of a page printed on regular paper that shows an underlying scene that&#8217;s from our timeline, but exactly the same layout.\u00a0 Or similarly, imagine lifting a die cut page and seeing that parts of one timeline have been &#8220;showing through&#8221; into another.\u00a0 It&#8217;s a concept that&#8217;s hard to describe verbally, but it for sure got me thinking about overlays and cutouts.<\/p>\n<p>At the same time, I wound up reading a children&#8217;s book that was based on overlapping transparent layers. If you have a child that likes to read, you know that they fixate on particular books for seemingly no reason and then want to have them read over and over.\u00a0 About the time I was stewing on this <em>Darwinia<\/em> stuff, my daughter decided that her new favorite book was going to be <em>The Adventures of the Three Colors<\/em> by Annette Tison and Talus Taylor. I Googled this book and couldn&#8217;t find much written about it. It was a book of mine from when I was a kid and the inscription in the front is from my father&#8217;s trip in 1977 to the Hirshhorne where he presumably purchased the book in the gift shop. The copyright though, is 1971.<\/p>\n<p>The book&#8217;s premise is simple: the main character, Herbie, sees a rainbow and then wants to paint a picture using all the colors he&#8217;s just seen.\u00a0 He finds though, that he only has three colors available: yellow, pink and blue. The book then shows how he can use these three colors in combination to create a full spectrum of colors. If you know anything about printing, you&#8217;ll immediately recognize these three colors as the CMY of <a href=\"http:\/\/en.wikipedia.org\/wiki\/CMYK_color_model\" target=\"_blank\">CMYK printing<\/a>: <strong>c<\/strong>yan, <strong>m<\/strong>agenta, <strong>y<\/strong>ellow and <strong>k<\/strong>ey (black). In these days of digital printing, unless you work in a print shop, you&#8217;ve probably never seen a CMYK color separation&#8211;and certainly not the actual inked plates.\u00a0 I&#8217;ve had a basic understanding of the theory, but I&#8217;ve never really seen it up close and in action until I re-read this book.<\/p>\n<p>What&#8217;s novel about <em>Adventures of the Three Colors<\/em> is how this is demonstrated. The book uses sets of transparent overlays in each of the three colors&#8211; and each with an animal drawn on it&#8211; which combine such that they overlap forming another animal in a new color. It makes more sense to see than to describe.\u00a0 Here&#8217;s an example of the first (and most basic) animal\/color combo:<\/p>\n<p><a href=\"http:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_01.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"2418\" data-permalink=\"https:\/\/www.benzilla.com\/?attachment_id=2418\" data-orig-file=\"https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_01.jpg\" data-orig-size=\"750,568\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;}\" data-image-title=\"colors_01\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_01-300x227.jpg\" data-large-file=\"https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_01.jpg\" tabindex=\"0\" role=\"button\" class=\"aligncenter size-medium wp-image-2418\" title=\"colors_01\" src=\"http:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_01-300x227.jpg\" alt=\"\" width=\"300\" height=\"227\" srcset=\"https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_01-300x227.jpg 300w, https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_01.jpg 750w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>Cyan elephant on the first page, yellow dog on the right.\u00a0 Overlay them and&#8230;<\/p>\n<p><a href=\"http:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_02.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"2419\" data-permalink=\"https:\/\/www.benzilla.com\/?attachment_id=2419\" data-orig-file=\"https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_02.jpg\" data-orig-size=\"558,750\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;}\" data-image-title=\"colors_02\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_02-223x300.jpg\" data-large-file=\"https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_02.jpg\" tabindex=\"0\" role=\"button\" class=\"aligncenter size-medium wp-image-2419\" title=\"colors_02\" src=\"http:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_02-223x300.jpg\" alt=\"\" width=\"223\" height=\"300\" srcset=\"https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_02-223x300.jpg 223w, https:\/\/www.benzilla.com\/uploads\/2010\/11\/colors_02.jpg 558w\" sizes=\"(max-width: 223px) 100vw, 223px\" \/><\/a>Green fish!
