The grey on my Myford is no longer the same as the fixed steady which has been in a box in the dark for the last 20 years or more. I don't use it often. But the main paint of the lathe is either faded or oxidised or Both. If you have a sample piece like a cover or accessory, they can scan it these days and make a matching colour. New paints also have UV stabilisers in them, something that may not have been in the original paint.
