My answer is that I don't care, I am color blind when it comes to loads of wood chips. I'm not into hot composting, trying to break things down bacterially as quickly as possible. I got two loads of chips today, and I will inoculate them with fungi and let time cold
compost them naturally. It will take some time, but right now I am digging into the piles of chips that were dumped here two years ago. Scrape off the top few inches of sun-dried wood chips, and there is glorious black humus that I am using to build up my hugelbeds.
