Color changes the way we perceive objects. Corporate companies know this and use it to their advantage. A couple examples: the color red is used to catch attention (stop signs, bike reflectors) and the color green is used to represent calmness, nature, healthy things. The picture to the left shows Johnson's baby lotion. The bottle was made pink probably because the company wanted to portray a feeling of softness and comfort. Pink also reminds me of baby items due to its strong reference in girl baby clothing. Companies think of all these things when creating a product and deciding its color.
In the second picture each gift card has different colors that have been assigned to a company. Each company has chosen colors that would best represent its motive. The cards shown are cell phone minute cards. Most cell phone companies have chosen bright colors to catch the attention of their customers. Repeating colors are also used to get customers to relate those colors with that company.
Color has everything to do with product design and is an important part of how we as customers perceive things.
