Sea coral can be many colors, but decorative coral is often red and so most people refering to "coral" are referring to that shade of red. Mix a smidge of blue (extremely little) into red to make coral red. It would be easy to use too much blue so try just a dot. If you've gone into purple, violet, or even violet red you've gone too far into blue. Mixing some violet into red would be a safer bet.
Red + Yellow = Orange Blue + Yellow = Green

No, they do not. The proper way to make orange would be yellow and orange, or yellow and red.
Yellow, orange, and dark green
Red and Yellow make Orange. Blue and Yellow make Green. Therefore, I would say that you need to dilute the orange with more yellow to get back as close to yellow as possible, then add blue.
Yes
Orange mixed with green will create a shade of brown due to the combination of the warm tones in orange with the cool tones in green.
