Pink is like yellow, but not quite

While promenading near the university campus, I was stricken by the view of a tree with no leaves but full of yellow flowers. Not having my camera at hand I resigned to memorise the sight and promised myself to come back with a camera. It took me a while to actually return.

'cause pink is my favourite crayon

I found what I think is the same tree, only flowers had changed colour, or perhaps I never really found the three again. Still, the pink version looked cool enough.
