Well, you did catch it, more or less. The most obvious part of it being the purple at the lower right. It's a bit unfortunate, though, that the blue band of the rainbow is above water, and the green band is above grass and/or its green reflection in the water! The red is more visible, and the purple can be made out...
After having read Anastasiatheo01's comment on how she percieves the rainbow and how it was positioned, I was inclined to agree with her, that is until I began to compare it to the colors of the water and grass over on the left, and realized that the two were very different, and of course only reason that would be could only be attributed to the fact that you acutally did catch the rainbow and I believe that you should get the pot at the end of it :) .....it's very pretty and prettily presented ;)PJ
It's pretty in any case!
