Blue is one of those colors that works well with everything and can be used in almost any design. It can work well with both graphic and abstract designs and can be used in the sky or ocean areas of your design along with some white space to create a contrast between the graphic elements. Also, blue is a good choice for logos because it is a very safe color and will not clash with any other colors in your logo. It is a very popular color choice for day-to-day office applications because it doesn't compete with the other colors and can make your office look more professional than just an eye-catching red or green logo.
Blue is also a very versatile color to use on any kind of product. In some cases, it's used as a complementary color for yellow (which has a lot of its own symbolic significance). For example, the colors blue and yellow are often used to make traffic signs appear more friendly and trustworthy.
