Wikipedia color info
Grey or gray is an intermediate color between black and white, a neutral or achromatic color, meaning literally a color "without color." It is the color of a cloud-covered sky, of ash and of lead.
The first recorded use of grey as a color name in the English language was in AD 700. Grey is the British, Canadian, Australian, Irish, New Zealand and South African spelling, although gray remained in common usage in the UK until the second half of the 20th century. Gray is the preferred American spelling since approximately 1825, although grey is an accepted variant.
So these are very common around here, used to be common as ashtrays, now often used as catch alls for things like paperclips. This abalone shell is about the same size as my hand with all the fingers spread open. Here a lot of people go abalone diving, but it requires a bit of a drive to get to the areas where they dive as they don't ever seem to actually dive for them along the coast with 4 hours of here.
When all candles be out, all cats be grey.
