Falling exactly between green and yellow on the color wheel, yellow green straddles the line between warm and cool tones. The vibrant effect is often called chartreuse or lime. When used in design and fashion, the bright, cheerful vibe of this hue evokes the new greenery of spring buds. It began showing up in silk and velvet accessories like scarves, shawls and purses in the late 1800s. During the flapper era of the 1920s, it was seen as a rebellious shade and became the de rigeur dress color among young fashionistas. During the 1960s, it was a mainstay of the psychedelic color palette and it also found favor among the bright neons of the 1980s. Today, yellow green looks fresh and modern when paired with neutrals like metallic pewter and crisp white. Neons have been on trend for several seasons and this is a universally flattering one to choose for both warm and cool undertones. Pair with magenta, its complementary hue, for an eye-catching outfit that highlights both shades. Home decor has been all about nature-inspired palettes for several years now, and yellow green fits right in with this aesthetic. Try painting your walls in a muted shade for an invigorating but not overwhelming effect. In its brightest form, it provides a trendy pop of color when used for a statement chair, accent wall or throw pillows and accessories.
