RLM colors with Tamiya Acrylics

Hi people, first of all MERRY CHRISTMAS to all

 Now the question: searching in the forum I've found a conversion chart of RLM to Tamiya the problem is I don't understand the conversion for the RLM83, they say

RLM 83:- XF61 or XF24:1 + XF51:1 or XF24:1 +XF51:1 (Dark Green)

so wich colors to mix XF24 or XF61 or the XF61 is a good match for the RLM83?

ipmsstockholm.org indicates that RLM83 should be FS34138 which is Tamiya XF26

Thanks
