Orange spans hue 15°–45°, the tertiary family between Red and Yellow, with 1,398,016 RGB colors. Amber, rust, terracotta, apricot and tan all live here. Its centre is #FF8000. This is the register's busiest family by named colors, largely because so many earth pigments and skin tones fall inside it.
Every registered tint, tone and shade of orange, ordered by luminance.
These are everyday names, not ORCN categories. Each one links to a
list built from the color name, so its colors may sit in more than one Color Family.
