The exact colours called for by official orders that would be existent during BoB would be these three:
02 grau
71 dunkelgrun
65 hellblau
Note though as early as August exceptions were beginning to appear. Just as the British were going through a period of colour change so too was the Luftwaffe, but these were unofficial and were more field "experimentations". Luckily the Brits kept better notes on captured aircraft and one will find more detailed descriptions on the use of mixed greys on Emils.
I suggest this web site, 109lair - more detailed, very informative read and will give some exceptions to the rule.
Interiors I had to check some old kit instructions; would be the same 02 grau and Tamiya points out the floor itself would be German grey XF-63 so I imagine this is RLM 66 schwarzgrau. The E-3 canopy framework interior could be either 02 or 66.
A couple other colours to consider are:
04 gelb - yellow tactical/identification markings
70 schwarzgrun - prop hub
