It is not too bad actually. The feeling that I'm getting from yellow is neutral as it complements the mustard yellow on the kimono and the gold obi. However it doesn't stand out too much unlike the red co-ordination.
The yellow obi-age is just a plain one with a woven hexagon pattern so there is no way I am going to be able to get photo of the pattern. As for the obi-jime, it is a sparkly gold one and the other side is silver so when you tie the knot you will get two colours. I can't decide if I like this obi-jime, don't get me wrong, I like metallic shiny stuff and this obi-jime tick those boxes. However it is stiff so I am never sure if I have tie it enough. One does not want their obi to fall apart when you are walking about in public.
