My heart leaps up when I behold
A Rainbow in the sky:

So was it when my life began;
So is it now I am a man;
So be it when I shall grow old,
Or let me die!

The Child is father of the man;
And I could wish my days to be
- 'The Rainbow' William Wordsworth

I spotted these roses at a florist in Bruntsfield - a case of real life photoshopping! Cost quite a lot too.... but then I wouldn't be surprised as I'd think this was rather tricky to do :)
