Here's what happened:
(I uploaded a larger image than usual because I'm not very worried about anyone stealing this one. If someone did, I think I'd just be incredibly flattered)
Something that threatens many watercolor-technique artists is what Barron Storey calls "your whites getting cold on you." That is, when you slap a little white paint on top of a perfectly good painting, it often looks kind of blue. The problem with THAT is that, more often than not, when you want an area to be lighter it's because you want it to feel like it's coming toward the viewer to some degree, but if that lightened area looks colder than the surrounding colors then the effect doesn't work very well.
In a nutshell, I spent a week (that I didn't have) learning to paint opaque colors over my transparent washes without it looking weird. For the most part, I did an okay job.
Thanks for checking it out! Stop by next week for another APE-ic post :O
