If you had, in front of you, a range of different coloured pens, which one would you pick out to write in?
Qualities associated with different colours spolier'd to avoid tampering with results:
dark blue - concerned with future, friendly, soothing
light blue - sensitive, emotional, spiritual
green - adaptive, harmonious, concerned with humanity/society, investigative mind
purple - theatrical, concerned with own uniqueness, need to be noticed, likes fashion
red - bold, aggressive, desire to shock, actively takes control of responsibilities, strong
orange - creative
yellow - concerned with discovering own identity, uniqueness
What would be interesting is if people would say which they chose, then say if they think the description is accurate.
In everyday life, I generally write in green or purple. I think the description of green is probably more me, but purple is not. If I had to pick at random, I'd probably go with red. That's probably not me, except on the third description.
Edit: If anyone's interested, there are some more psychologically derived colour analysis available free online, based on the Luscher colour test. Try the one here, if you feel inclined. Again, perhaps you can share if you think it's accurate or not. I've taken it a few times at different stages, and at least one came out very accurate, and one came out inaccurate - so it's sort of an inconclusive result from me.
