A shade on a monitor and a shade on a model are two different things. Printed charts and colour guides show the tone on paper, often tied directly to a specific machine and its documented finish.
They earn their place when you are planning a camouflage scheme, comparing shades from different lines against each other, or simply deciding which jars to buy in the first place.
Lay the chart next to the model in progress and compare under daylight rather than a warm bulb. Treat the printed tone as a guide to the choice, not as a verdict: scaling down optically lightens a finish, and the sheen of the final clear coat shifts the impression again. The jars matching your chosen shade are listed in the model paints overview, while deeper research into finishes and their history usually belongs to the publications in the modelling literature section. The machine you are chasing a chart for can be found among the aircraft model kits.
