Vallejo Xpress Color Nuclear Yellow 
Paint glowing energy, bright armor, magical effects, and bold fantasy details with fast, vivid yellow contrast.
Vallejo Xpress Color Nuclear Yellow is a transparent acrylic color designed to flow naturally over miniature surfaces, creating light raised areas, saturated mid-tones, and stronger shadows in the recesses with a single expressive layer. It is ideal for fast tabletop painting, luminous details, and high-impact yellow effects.
 
What it does
Creates a bright nuclear yellow tone with instant contrast and intensity.
Works especially well over white or grey primer, where the color naturally separates into highlights, mid-tones, and shadows.
Excellent for glowing weapons, magical energy, hazard markings, armor panels, banners, gemstones, lenses, and fantasy creatures.
Can be used for glazes, filters, soft shading, contouring, and blending transitions.
Can be mixed with other Xpress Colors or diluted with Xpress Medium to create softer yellow tones and custom shades.
 
How to use
Prime or basecoat the miniature in white or light grey.
Shake the bottle well before use.
Apply with a brush and let the paint flow naturally into the recesses.
Avoid overworking the surface while drying to keep the contrast clean.
For softer or more controlled results, dilute with Vallejo Xpress Medium.
It can also be used with an airbrush for tinting, filters, and smooth color effects.
 
Best for
Glowing yellow magic, spell effects, plasma, and energy weapons
Hazard stripes, sci-fi panels, lenses, screens, and warning details
Bright armor, banners, tabards, shields, and heraldry
Toxic creatures, demons, elementals, mutants, and fantasy monsters
Fast tabletop painting for Warhammer, D&D, Pathfinder, skirmish games, and board game miniatures
 
ChalkyDot Tip
Use Nuclear Yellow over a white or zenithal prime when you want the brightest result. For glowing effects, paint the surrounding area with a thin yellow glaze, then add a small off-white highlight at the center of the light source to make the glow feel stronger.
