The colours you see in the first photo are very accurate shades of gold, in in some small areas of yarn the grey pops thru as a light gold or the grey has hints of green yellow very light in colour.
All these yarns have  lustre ,good handle, drape would suit any projects small or large as in a vest.
None of these yarns can be reproduced that is why I did 2 kilograms did not dye measures just mixed primary colours.
