And you can see the trunk of a palm tree in the background, so that clinches it.

Pretty saturated yellow, eh?  Almost good enough to eat.  Certainly good enough for a photo, and would a painter be accused of exaggerating the color?  The sky blued itself up today after a gray start, so the high contrast and the rich greenery and fluff of cloud are nice counterpoints.  Thank you, Mother Nature, once again!
