Ive posted this in both the painting & armor forums.

Ive tried to use Model Master Panzer Dunkelgelb 1943..Its seems so green?
or is it just me?, any recomendations on how to mix for proper shade?
or do they make a better color?

I have Tamiya Dark Yellow which in my opinion, is a closer match..but
I have a fear of using Tamiya and MM Acryl on the same model.

Oh by the way, this is for the three tone (yellow, green, red brown)
Tamiya Panther G late version.

I thought the MM was very green also. I wouldn't worry about using Tamiya over MM, I've done it with no real adverse effects. Or, maybe you could try adding some more yellow to the MM to brighten in up some.
Vallejo's Dark Yellow comes out the same way. Funny.

I prefer Tamiya XF-60. I also think that MM dunkelgelb is too green.
