Hi Maciej - If you are asking whether Humbrol Hu 29, Hu 30 and Hu 90 is a good match for DuPont 71-009, 71-013 and 71-021, I don't know. My hunch is that it will take some digging to figure that out. Sounds like you like your Humbrol paints, so ignore the following if that's what you are going to use regardless.
I am not sure how accurately the Humbrol paints were formulated to match the original wartime colors. A lot of new work has been done in last 20 years on understanding wartime paints colors, and on model paints consequently. I am currently reading Real Colors of WWII from AK Interactive, so this topic caught my eye. I am pretty excited about their new Real Colors range and the amount of work that went into their formulations. I have not yet tried them, but definitely on my list. There of course are other, newer options as well (Mission Models, Life Color etc.). Just food for though...
This is going to be a great build
