Monochromatic branding is often minimalist and refined. A monochromatic brand color palette contains various shades of the same color. You start with a base color and add different shades through font, images, icons, materials, etc.
Monochromatic colors create a cohesive look for your brand and generate a soothing sense of tranquility. The primary color you choose establishes the rest of your brand color palette. So, choose a color relevant to your industry that embodies your brand personality.
