I'm actually kind of excited for this choice, despite not developing a fondness for green until earlier this year, and then gravitating to muted shades in action. Can't explain the insta-love ...but I welcome it
Scientifically speaking, color is divided into three components: hue, saturation and tone. Emeralds occur in hues ranging from yellow-green to blue-green, with the primary hue necessarily being green. Yellow and blue are the normal secondary hues found in emeralds. Only gems that are medium to dark in tone are considered emerald; light-toned gems are known instead by the species name green beryl. The finest emerald are approximately 75% tone on a scale where 0% tone would be colorless and 100% would be opaque black. In addition, a fine stone should be well saturated, the hue of an emerald should be bright (vivid). Gray is the normal saturation modifier or mask found in emerald; a grayish-green hue is a dull green hue.
Emeralds are green by definition (the name is derived from the Greek word 'smaragdus', meaning green). Emeralds are the green variety of beryl, a mineral which comes in many other colors that are sometimes also used as gems, such as blue aquamarine, yellow heliodor, pink morganite and colorless goshenite.
I love green!! But I'm not a fan of emerald (well, only in certain objects) but this looks emerald to me. Kelly is more yellow. I like kelly. This color has more blue, making it more emerald. I do see how it could be darker
