..what did you mean by RLM ?
The German AirMinistry
(
Reichsluftfahrtministerium; RLM) had a system for aircraft designation which was an attempt by the aviation authorities of the Third Reich to standardize and produce an identifier for each aircraft design's airframe type produced in Germany. It was in use from 1933 to 1945.
The RLM determinated the LW colours as well as the camo schemes for all planes being used by the Luftwaffe. Therefore you may find the name in many references talking about the LW colours.
As Crimea River had stated it above , the RLM main set of colours for Fw 190A was 74/75/76. The set was used from 1940-1944.
Unfortunately the Tamiya dosn't offer the exact equivalents of the RLM paints and mixing of colours is required if you want to get the correct shade of these.
Tamiya spray paints ...
AS-3 Gray Green = RLM 74
AS-4 Gray Violet = RLM 75
AS-5 Light Blue = RLM76
Mixed equivalents...
AS-3 ~ XF-18 + XF-26 (3:1)
AS-4 ~ XF-24 + XF-18 + XF-9 (7: 3: 1)
AS-5 ~ XF-23 + XF-19 (4:1)
