This is actually pencil on paper, just inverted and colored

Inverting colors is a method of image manipulation where colors are switched with their opposites; Black becomes white, red becomes green, orange becomes blue, and so on. To create this image, Randall tells us in the title text that he drew the outlines of the flowers and stems with pencil on white paper. He likely next scanned the drawing and used image editing software such as Photoshop to invert the black-on-white image, producing white lines on a black background. Next, he may have printed the image out and colored it before scanning it again or added the color using software.

See the article Inverted Colors Photo Effect With Photoshop for a detailed example of how this is done.


  • Original quote from Randall: "Original drawing is pencil on graph paper. Bonus points if you can identify the flowers. 'cause I sure can't."
  • Original guess on flower identification: "Trillium!"
  • This is the thirtieth comic posted to livejournal. The previous was 30: Donner. The next was 29: Hitler.

Instructions for photoshop editing is quite irrelevant here, I think. The comic itself is just a drawing of flowers, and hardly needs much explanation (if any). –St.nerol (talk) 18:21, 19 January 2013 (UTC)

Correct. I'm working on this comic because you did not;)--Dgbrt (talk) 22:38, 10 June 2013 (UTC)
Shit, shit, shit... as Randall would say, but finally I could upload my edit. It's still not complete.--Dgbrt (talk) 00:54, 11 June 2013 (UTC)
As I remember it, I removed the "explanation" that was, which wasn't popular. So I just let it be... ––St.nerol (talk) 10:23, 11 June 2013 (UTC)
Check the history, your edit was reverted. When you have problems with some pages do not only tell us what's wrong, just try to give an better explanation. Without a new solution these discussions are meaningless. Everybody is doing mistakes, but the magical word is UPDATE not DELETE.--Dgbrt (talk) 13:56, 11 June 2013 (UTC)
Yeah, I know it was reverted, that's what I meant. I will improve stuff when I have time and knowledge to do so. Sometimes I will also delete stuff. It's a balance to strike, and often quick decisions, but my intention is always to make the wiki better. ––St.nerol (talk) 22:18, 11 June 2013 (UTC)

Dgbrt, I did not remove content, I removed redundancy. One sentence about graph paper instead of three. Clearer, shorter wording about botany and picture editing, but no less informative. - Frankie (talk) 20:57, 22 June 2013 (UTC)

Hi Frankie, you did remove the incomplete tag. We still have to review pages like this. But your enhancements are welcome!--Dgbrt (talk) 21:13, 22 June 2013 (UTC)
