Picture Of 2 Particular Swiss Stamps

I would like to see a picture of the 2 following items :
1- Rayon II Zumstein 16 II (Tobacco) / Michel 8IIb (Tobacco)
2- Rayon I Zumstein 15 IIb (violet-blue) / Michel 7IIc (dark ultramarine)
Because the pictures from my catalogues are not very clear and I cannot make a very clear difference with a similar but much more cheaper stamp of the same set.

I you have such stamps or a picture showing clearly the color nuance, please could you upload it here ?
Thank you

Is this one of them?

NO, it is not !
That is the standard Rayon II (yellow) but not the nuance "Tobacco" which should be dark Brown-orange.
Thanks for searching

?



Hahaha! If I'm wrong, I'm giving up. These are hard varieties to find!

Again, I don't think that that is the "tobacoo" nuance which has to be darker and more Brown.
But thanks for your help !
