The significant difference here is that images seem to be rendered differently to paragraph background colours. With images readers seem to dither their 8 or 16 greys, which is what you would expect from image rendering with a limited palette.

However, with background-color style there seem to be different approaches. My PRS-300 dithers, hence the 'smooth'/'grainy' results, whereas other readers seem to snap to the nearest grey that is not dithered. Both methods are valid but produce different results.

I'll test more with my PRS-300 and KPW to try and find a good compromise - at least I can ensure that my grey background paragraphs don't end up white!

Thanks for all the info.
