Making it Work: Flat Design and Color Trends - Designmodo
Flat design relies heavily on color choice to create visual impact, with three main trending approaches: bright, fully saturated colors that pop against any background; retro tones that mute bright hues with white for an old-school feel; and monotone schemes that use a single base color with black and white tints for contrast. Rather than following traditional color-pairing rules, flat design palettes prioritize matching tone and saturation levels across multiple colors while maintaining enough contrast to guide users and create visual interest.
