The colour "Blue" in Chinese Culture

Hi,

Can anyone tell me the value and or significance/meaning of the colour "Blue" in Chinese culture, ranking etc?

I am very interested in this form a cultural and Martial Arts level and would appreciate any and all information and discussion.

Hi Shifu,

Light Blue and white are not a lucky colour in most of the Chinese People (May be only applied in Hong Kong). They usually use this colour in Funeral.
