Better Wood Colors

This simple pack makes Spruce Planks and related items such as signs and boats look gray for being used to build old shacks, horror mansions and such, while Bamboo Mosaic looks just like wood planks of the same green of live Bamboo plants, because apparently people want green planks (other bamboo blocks are still yellowish to get more variiety).

This pack is open to suggestions. Which wood would you change?
