Forgive me for not reading through the entire thread...
But have we talked about the colour yellow at the reception? (probably have)
But right now I'm watching a re-run of TSo3 and I was admiring the walls... beautifully decorated. huh! But the colour yellow made me think.
I sometimes use 'flower language' in my writing... it's like leaving a little clue for people who knows what it's all about. I especially use yellow roses quite a lot. Yellow roses seem to have different meaning depending on where you look.
Yellow roses either symbolizes lies... or friendship. I usually use it for the first.
I do know it's a wall, and not a rose.
