The red heart shape is painted on most likely Chara's coffin in castle basement. Also, monsters can see human soul, otherwise they would'n be able to attack it or simply hit it. Now, the question is: do monsters must enter in some battle mode to see the soul or do not? Asriel knows exact Chara's soul color because he absorbed it after their death. However, he didn't share this knowledge with anyone.
