204 opaque colors weighted toward historical and scale-modeling work.

Understanding Model Color
Model Color is Vallejo's flagship range and the larger half of its two-range lineup, 204 opaque colors in dropper bottles. What defines it is the bias: browns, buffs, and earth tones make up the single biggest block of the range, with a deep bench of greys and muted yellows behind them. This is a palette built for uniforms, leather, wood, stone, and camouflage more than for bright fantasy.
That focus is why scale modelers and historical painters reach for Model Color first. The range is full of the specific desaturated tones, field greys, khakis, weathered browns, that those subjects need and that a fantasy-first range tends to skip. The dropper bottles suit precise mixing and wet-palette work, which is how most of these colors are meant to be used, in small controlled amounts rather than straight from the bottle.
If you paint fantasy or sci-fi miniatures, Model Color still works, but you will find its saturated colors thinner on the ground. That gap is exactly what Vallejo's Game Color range exists to fill, so the two are best understood as a pair.
