Is the correct spelling "grey scale" or "greyscale"? I'm not sure whether or not to write it as a compound; it's in the context of a black-and-white video stream.

The OED entry for greyscale shows a familiar progression of compound formation. The earliest entry, from 1857, refers to grey scale; from 1961, there is a citation about a grey-scale chart, and by 1994 there is a mention of greyscales.
A quick Ngram of variations of greyscale image (in order to exclude most scales which are grey, and Martinian afflictions) shows all three forms in use, but the closed form being most common for both gray and grey.
