Opaque Colors are solid colors intended to cover underlying colors and surfaces with 2 – 3 coats. Opaque Colors make excellent base colors. For many projects, starting with either Opaque White or Black works best as other colors types will cover quicker with vivid, brighter effects compared to applying colors, for example Pearlized or Transparent, direct to substrate without base of opaque White or Black. Opaque colors work best with larger tip-sized airbrushes operated at higher PSI settings. For fine lined detail, lower PSI settings and small tip-sizes, Transparent Colors work best.
