Colorgenics
I initially thought that the idea of using colour selection to determine (what I assumed was) personality type was interesting and probably insightful, but ultimately a minor psychological trick. Until I tried it and it spat out not a personality profile so much as a description of my current mindset exactly. Try it.

Edit: As Penn Llawen has pointed out, it almost certainly just the Forer Effect (which I had previously only known as Barnum Statements - a hat tip to you, sir). A few paragraphs from the relevant Wikipedia article back it all up:
Color psychology is an immature field of study viewed dubiously by mainstream psychologists and therefore qualifies as “alternative medicine”. Critics view it as an overstatement of what can be justified by research, and point out that different cultures have completely different interpretations of color.
This is what happens prior to the first cup of coffee, people. Be warned.
