Purple is a spiritual color, crown chakra color. Maybe it spaces you out too much? Also people who have purple as a dominant color in their auras have a second color that balances it out...I think for purple its yellow. Try adding some yellow accents...anything, a tapestry, stuffed animal, shirt..etc. No painting needed.
Lighting makes a difference too, full spectrum lights are more like the sunlight we are supposed to get. Those yellowish lights are great for evening but not midday. I have a light that I bought from
www.mercola.com and its great, no eye strain or anything and you can't really tell it from sunlight because it has the same spectrum of light.
