Blue spruce tree and biome

Minecraft has many unique looking leaf types to choose from but there is a problem and that is a lack of color variation and that´s why I propose the blue spruce. It would use the same old spruce wood that´s already in the game but it would be slightly bigger and would spawn with the new blue spruce leaves. They would obviously be blue and would either use the same texture as regular spruce or a similar one. There would also be a blue spruce sapling. These new trees could either be found lightly sprinkled alongside regular spruce trees or in a new biome in which their roles would be switched and the regular spruce trees would be sprinkled alongside the blue spruce trees.
