Poem in Pink

A salt lake in Melbourne, Australia recently turned pink due to the growth of algae “in response to very high salt levels, high temperatures, sunlight, and lack of rainfall.”  The phenomenon transformed the lake from its natural blue tone to an unusually bright flamingo color. Write a poem that begins by evoking the sensations of one color, and then—gradually or abruptly—turns a strikingly different color, perhaps even pink. How will you manipulate the mood, images, sounds, and rhythms of your language to reflect the color change?
