Use Blue
If I were designing a school uniform, I’d choose a clear sky blue for the shirt, and a navy for the blazer and bottoms. Why? Blue is not only grounding, and helps give confidence and reassurance to those wearing it and those seeing it, but the range of blues can be harnessed for study and work.
Sky and light blues can help bring inspiration and ideas when you’re feeling a bit stuck, and a darker blue, or navy, helps improve focus and concentration. In designing this website, I was wearing a sky blue shirt and a dark blue jacket. Try it next time you’re struggling to concentrate, or need new ideas, and see how it helps your work.
