It is indeed both red and wood.
Wonder if the same dude calls oak orangey wood?Also, not looking to pick holes in the very thorough and sound advice that @Airhead takes the time to contribute on here.
I don’t know anything about 95% of it but I do know the difference between redwood and Sapele so thought it worth pointing out to avoid confusion for anybody wanting to buy Sapele and ending up with pine.
Sapele is what is sold instead of mahogany, it is a bit red in colour but it's not a type of pine. (redwood)
You often see Sapele being used as the cill and rest of frame and casements made from softwood/redwood/pine species.
