Douglas fir
Yellow fir and red fir are both the same species. (douglas fir) It goes like this they are identical until the tree reaches a mature age.(Somewhere between 80 and 180 years old, depending upon location, elevation and soil type) Then the outermost growth rings start to reflect a yellow color. Prior to this stage the wood is red. So a red fir turns into a yellow fir once it reaches a certain age. Any subsequent growth will be yellow wood. The heartwood and any inner rings will remain red. The yellow colored wood is put on as the tree continues to grow.
