This study examined comparatively the color ``white`` in Ancient Korean Literature and Manyoshu. Findings are as follow. First, in Hyang-ga white cloud is shown only in Changiparang-ga. It is argued that the white cloud is used in spiritual rather than scenic sense since it indicates noble personality of giparang. Second, white is the color of darkness. White virtue·white rainbow in Samguksagi reminded of white silk. It is therefore argued that the white color is identified as omen implying bad accidence such as a death of king or a national crisis Third, the white horse and white chicken in Samguksagi and Samgukyusa reflect sun-worship thinking. The white wolf and white dog show the sign of king`s death or national crisis. The white horse is used as sacrifice for god`s rites and its blood is used for a vow. Thus it is estimated that the white color is related to the meaning of pledging to the heavens. Fourth, the white color is shown frequently in Japan`s Manyoshu. ``Sirotae(白고)``, in linkage with other words, is used in the sense of daily clothes, affections, or mourning dress. Fifth, ``white waves`` in Manyoshu`s works is mostly either songs of simply scenery or songs of love affairs. Frequent usage of ``white waves`` indicates the characteristic of oceanic culture of the Japanese. Sixth, ``white dew`` in Manyoshu`s works compares to the vanity of love in relation to its attribute that it soon disappears whenever dew drops or sun rises in the morning, together with its seasonal sensation. Seventh, ``white cloud`` in Manyoshu`s works is often used with high mountain. It shows a sense of distance from home, a spatial sense of distance from one`s loved one, a picture of hiding old home deeply, or a scene of hanging on cloudy mountain. From these, it is argued that ``white cloud’ is used with the meaning of thinking the other party always. Eighth, white vigor and white animals are shown in 古事記 and 日本書紀. Unlike Korean cases, they do not have the function of foretelling future events.
