member :RED
member :GREEN
member :BLUE
end
{ color: Color::RED }.to_json # => "{\"color\":\"RED\"}
Color::RED.red? # => true
Color::BLUE.blue? # => false
Color::RED == Color::RED # => true
Color::RED == Color::BLUE # => false
Color::RED == :RED # => false
Color::RED == "RED" # => false
Color::RED === Color::RED # => true
Color::RED === Color::BLUE # => false
Color::RED === :RED # => true

Color::RED.match?(:RED) # => true
Color::RED.match?("RED") # => true
case "RED"
when Color::RED then "#FF0000"
