Willeke,
It is difficult to choose. Not only color, but flower style.
There are many different seed sources, but if it where myself buying obesum seed right now. I would go with Adenium_ko or Rinoa (Orient Adeniums), both from Taiwan.
I state this, as many people are having very good results with seed from these vendors.
David Clulow has shown quite a few different crosses he has done using trees (blooms) of Rinoa's and Ko's with some nice results.
Was trying to find the information that I used to have on Color selection and which colors cross best with each other.
Adenium_ko has some nice photo of pod x pollin parent crosses he has done. This seed is available.
I have been concentrating on Species and Arabicum/TS seeds in the past few years and have not purchased obesum seeds to date. Acquaintances do a lot of buying from these two.
Hope this helps to narrow it down to vendors for you.
See if I can add the link for Ko

Rinoa has a seed list. Search "Orient Adenium Seeds" and there is a website and it will take you right to her On-line Seed list.
