colours of ONCF

Hi all, I'm new to the forum and I thought, that there might be an expert regarding ONCF here around. I tried to find out what colours ( name of colour or RAL code ) ONCF used for their trains by searching the internet, but without success.
I'm interested in the colours they used for the following carriages:

Thanks in advance!
