RED
Interesting seems the connection between Slavic "ruda" meaning "ore" most usually "iron ore" and Finnic Livonian "rōda" meaning "iron".
The word "Ruby" representing a red gem comes from a Latin word for "red" namely "rubeus".
English verb "to roast" is also very interesting as it indicates a process of "turning red meat into a ruddy, rusty color" or simply "making meat brown".
