I had to go and check, and I can confirm that it’s OK. The sea is still blue, as is the sky, with a cleverly contrasting yellow for the ground. Whoever worked that one out is no fool, it gets us every time.
Times change, so I don’t know if parents are still afflicted with the persistent cries of “Are we there yet?” from children, desperate for their first view of the summer sea, as family cars slowly edge towards the end of land for their holidays. I remember uttering that cry and experiencing the excitement engendered by that first view of blue joining blue. In truth, it was often grey joining grey, but anticipation and imagination created the blues, that for once were not a lament but a joyful hymn.
