avery,.. could you "eyedrop" select the color from a digital image/schematic?,.. I think if you have the actual paint code it may look different as rgb or cymk versus that spot color? if it was professionally printed it could be more accurate i suppose,.. but with everyone having a different printer etc,.. i think you could get away with a close enough approach
