Black- Symbolizes sophistication and can make lower-end products seem more high-end.
Blue- Symbolizes trust and dependability. In a 2003 study published in the Journal of Business Research, customers were 15% more likely to return to a business with a blue color scheme as opposed to a business with an orange color scheme.
Orange- Symbolizes fairness and affordability. Usually used by stores where low prices are one of their top priorities.
Red- Symbolizes an alarm or stop sign, so customers may be more wary to spend.
Yellow- Symbolizes energy and increases appetite. This color is popular with fast-food restaurants who want you to make a last-minute stop as you drive by.
