Why is Sri Ram blue skinned and Sri Krishna dark skinned?

Why is Sri Ram blue skinned and Sri Krishna dark skinned? Originally Answered: Why is Rama Blue skinned and Krishna dark skinned? In Valmiki Ramayana Aranya Kanda, Maareechi describes the teenage Rama to Ravana - AjAta vyanjana sreemAn bAla shyAma subhekshaNAha, eka vastra dharO dhanvee sikhi kanaka mAlayA. Meaning: one with birthing identities of masculinity ( signs of moustache, ruggedness in face etc.), the fortunate boy with magnificent looks, smoky-grey complexioned, wearing a sikha (choti on head) & only a loincloth, holding the long bow with a golden necklace around his neck. and Akampana (Ravana’s spy) reports to Ravana that he saw Rama and describes him - shyaamaH pRithuyashaaH shriimaan atulya bala vikramaH, hataH tena janasthaane kharaH ca saha duuSaNaH Meaning: He is smoky-grey (or bluish-black) in complexion, a highly renowned one with matchless might and valour, a magnificent one such as he is, he slew Duushana along with Khara in Janasthaana. In Bhakti literature Ramayanas and Mahabharata they both were described as 'Neela megha shyaama', i.e. akin to the dark grey cloud. i.e they were both smoky-dark colored. Songs are still sung today on Sri Rama and Sri Krishna using this epithet. Please do not go by what they show in movies and TV shows, these entertainment sources are not correct. Go to the original source as i.e. Valmiki Ramayana and Vyasa Mahabharata, and you will see for yourself. *:A gentleman suggested that hindi alphabet with consonant together are worded as ‘Krs’ and not as ‘krus’ as I mentioned above. He is right in the sense that it is written that way in Hindi. But it is pronounced as ‘krushna’ & not certainly as ‘krishna’ in Sanskrit. So I made the edit above. The ‘kru’ is not to be pronouced as ‘kroo’, but the ‘u’ in it is pronounced as how you would pronounce the ‘uh’ in “uh oh”
