Color match needed.

I am building the Hasegawa Lancia Super Delta and the paint for the interior door panels is Gunze H61(IJN Gray),and the seats are H69(RLM75 Gray). Does anybody know a match in Tamiya Acrylics?

Tamiya J.N. Grey is XF-12 or AS-29 spray. RLM 75 grayviolet is only available in a spray AS-4 but I have seen a mix code for it of 3 parts XF-2 / 4 parts XF-24 / 2 parts XF-9. The lazy route would just be to use XF-54 Dark Sea Grey as it is a suitable warm medium dark grey colour.
