I have regained my quill on the promise that I reveal nothing further.

Also, I'm instructed to correct my statement: Narcissa's is not pink, either. (Apparently there is a difference between periwinkle and pink, and at any rate, she says she had rather Splinch herself than wear pink when Dolores Umbridge is likely to be at the gala. In the first case, I neither knew nor cared about the distinction; in the second, I can readily understand her adamant denunciation of the colour. It certainly looks pink to me, but I am assured I am wrong in this assessment.)
