A color palette refers to a set of colors used in design, typically to create a consistent and aesthetically pleasing look. A blue color palette often includes shades of blue, ranging from light sky blue to deep navy, and can be used in various design contexts such as graphic design, fashion, and interior design. The choice of blue hues can influence the mood and feel of a design, with lighter blues often perceived as calming and soothing, while darker blues may convey a sense of sophistication or formality.
