Logo design often incorporates color schemes that resonate with the brand's identity. Red and blue are two primary colors that have been widely used in logo design due to their strong visual impact. Red, often associated with energy and passion, can evoke emotions and convey a sense of urgency or importance. Blue, on the other hand, is often associated with trust, stability, and professionalism. The combination of red and blue can convey a balance between emotion and reliability, making it a versatile choice for logos.
