(WTVR) - Studies show that picking out presents may depend on what colors you see when you go into a store.
A study at Virginia Tech says that red stimulates and energizes our bodies, even our spending. It doesn't matter if a red shirt are on display or if there are red walls in the store.
However, the opposite is true for people who shop in a store with blue on display.
Green is an optimistic color associated with luck or wealth. The color has a more positive effect on creativity.
The study says it may explain the unusual gifts under the tree. Professors at Virginia Tech say the trend also holds true for online shopping.
