Virgos are control freaks. They regulate their breathing and hang clothes in the closet based on their color. They clean every square inch of every surface in their homes twice a day with a tooth brush and inspect the result with a magnifying glass. If you want to freak out a Virgo, tell them there is something between their teeth.
The only color shades they see is clean and dirty, but this is kind of cool, because they will eagerly do your laundry for you. However, don’t count on them if you want this done quickly, because they will separate everything by the color and fabric and then put the clothes in the washer in alphabetical order by the manufacturing brand.
