I Spy — “I Spy” is a popular children’s game, designed to help pass the time on road trips or other long and otherwise boring routines. As a color, however, I Spy is hardly boring at all — a careful mix of off-white grayish cyan undertones to brighten the overall appearance and give the hint of something hiding just beneath the surface. It belongs to the Light Grayish Cyan - Lime Green family, as it has a high lightness and saturation values, indicating it's a pale, muted color with green and cyan undertones.
