Using Color in Ad Design
This color is usually suited to businesses related to cosmetics, fashion, beauty salons and romance. With its softness and sweetness, pink is also ideal for candy stores and any business selling sweet products. Brighter pinks are useful for marketing less expensive and trendy products to the teenage and pre-teen girls; whereas muted dusty pinks work when promoting sentimental services and products, particularly to an older market.
Yellow
What do you think of when someone says "yellow"? Sunshine, buttercups, sunflowers, lemons, mustard? Yellow is a cheerful color and can be used to add a touch of luminousness. It's often used in food ads or designs, either along with red or with other complementary colors such as blue.
Use yellow to evoke pleasant, cheerful feelings and to promote children's products and items related to leisure. Many perceive yellow as a lighthearted, "childish" color, so it is not recommended in ads for selling prestigious, expensive products to men or high-end items targeted at the upper echelons of society (few people will buy a yellow purse or briefcase). That's why, in marketing, yellow often stands for "low-priced".
Keep in mind that too liberal a use of yellow can be jarring. That's why yellow is often used in warning signs or to indicate danger. It should also be avoided if you want to suggest stability and safety.
Green
The most common connotation of green is of course, nature or the environment: grass and leaves. As such, a liberal use of green can be soothing. It works well for outdoor products, vegetable stands and landscaping businesses because it signals life.
Green can also convey health and wellness. That's why hospitals and alternative medicines feature this color. It also signals freshness, so you see it in ads for detergents and cleaning items. It's even used for those items that keep us clean like shampoos, mouthwashes, toothpastes, etc.
