Def: Color-blocking is when a garment or outfit is composed of finite blocks of color.
There are three techniques to styling a color-blocked outfit – select one: Option A: Monochromatic = one color throughout entire outfit in different hues. Option B: Separates = mix garments of contrasting (2-4) colors. Option C: Stand-Alone = one color-blocked garment or accessory where the designer has already done all the work for you.
