Tamiya Mixing Instruction???

simple question.

Tamiya instructions

EX:
XF-9:1
+XF-50:2

Is this mixing instructions for their paints?

Never noticed it befor, but then again i am just starting to use tamiya paints since i got an AB

looks like they want you to mix two parts XF-50 (field blue) with one part XF-9 (Hull Red). You’ll still need to thin it out before spraying though.

ok, thanks.
