Sulf. Yellow

Sulf. Yellow: the pale sulphur yellow of RAL 1016

Sulf. Yellow is our name for RAL 1016 Sulphur Yellow (Schwefelgelb), a light, slightly greenish yellow from the RAL classic range. It is softer and cooler than signal or traffic yellows, which is why it appears on industrial equipment, public-transport accents, signage and warning details. Modelers use it for machinery, utility vehicles, rail and industrial dioramas, and for livery accents where a fresh, lemony yellow works better than a deep golden one.

The problem with bright colours

Reds, oranges and yellows are naturally translucent. Over a grey primer they go patchy or dull, and by the fifth coat the panel lines are gone. This colour is ground for strong coverage, so you reach full colour in fewer, thinner coats and the detail stays crisp.

How to apply

1. Shake the bottle for at least 60 seconds.
2. Prime with a white primer and let it dry fully.
3. Airbrush straight from the bottle, no thinning needed. Use a 0.2–0.4 mm nozzle at around 20 PSI (1.4 bar) and apply light, cross-hatched coats, letting each one flash off before the next.
4. Let the paint cure overnight before masking or clear-coating.
5. Seal with a water-based clear coat: gloss for a factory shine, or satin or matte for work vehicles and interiors.
6. Clean the airbrush with water before the paint dries.

Why modelers choose Koloi Aqua

• Ready to spray: no guessing thinning ratios, the same result from every bottle
• Cleans up with water, so there are no strong solvent fumes at the bench
• Fine pigment grind for 1:8 to 1:72 scales, so panel lines and detail stay crisp
• One system: primer, colour and clear designed to work together

Shelf life

Estimated shelf life of more than 12 months when stored tightly closed between +10 °C and +28 °C, away from frost and direct sunlight. Shake well before use; if the paint has thickened or separated and does not remix, do not use it.
