These paints are all specially formulated for use with GHQ models. They all have been toned down slightly to simulate the water vapor, dust, etc. that is present in the atmosphere when viewing an actual vehicle or ship from a distance. If you view a 1/285th scale model on a table from 3' away, that is the equivalent of looking at an actual tank from almost 900'! All of the dust and water vapor in the air catches light and tones down what you are looking at. Without the slightly toned down colors, your models will appear too dark, and not realistic. These paints are a must for obtaining realistic results with Micro Armour® and Micronauts®.
