Sweet Jade and Hella John
In fact, several other things are WIP. For instance, the formatting is a little screwed up. Until I get this figured out, I recommend checking out SJAHJ Thread.
Homestuck character images, such as John and Jade's sprites, were used from the templates on the Image Manipulations threads.
Quick mention goes to puppetfetishist for link on hex colors for each of the kids and trolls. Well, at first. Now I've been using the color tempalte sheet on the MSPA wikia.
