Yellow and purple are my favorite colors. I love this combo. I would probably switch it though so that Raisin is the predominant color.
I have seen an SO with Jaune d'Or and Violet in real life. It's a very strong contrast. Personally I did not find it appealing.
In this case I think the Raisin is not pop enough to match the Moutarde brightness if that makes sense. I do empathize, bec of the limited colors, how hard it is to select an SO order this round. Best of luck!
I have to say that this does not sound appealing to me. Yellow and purple are for Lakers fans. Agree that chevre colors are limited but there are other choices.
I also didn't see contrast panels available for K or B, only sangles, handle, piping.
