What are coloured glow sprays?
Coloured glow sprays are clearly tinted even by day and glow in the dark. Choose them when a surface should look coloured in daylight too. Keep in mind: tinted shades glow for a shorter time than the whitish natural shades, and strongly tinted shades also glow much more weakly.
Which colour gives which glow?
With coloured glow sprays, the daylight colour and the glow colour often differ. The name does not always tell you the glow colour: Orange-Yellow, for example, glows greenish and Pink a warm orange. The table shows all eight shades.
| Glow spray | Daylight colour | Glow in the dark | Glow strength |
|---|---|---|---|
| Yellow-Green | yellow | yellow-green | slightly shorter than the natural shades |
| Green-Green | green | green | slightly shorter than the natural shades |
| Orange-Yellow | bold orange | greenish | shorter and weaker |
| Terracotta-Green | warm, earthy terracotta shade | green | shorter and weaker |
| Blue-Blue | bold blue | blue | weaker and shorter |
| Purple-Blue | bold purple | blue | weaker and shorter, best charged with UV light |
| Pink | bold pink | warm orange | much weaker |
| Light Red | bold light red | greenish | much weaker |
How strongly do the coloured shades glow?
The more strongly a shade is tinted by day, the less glow remains in the dark. The eight sprays therefore fall into three groups.
- Yellow-Green and Green-Green: glow only slightly shorter than the natural shades. They suit you if daylight colour and a good glow matter equally.
- Orange-Yellow, Terracotta-Green, Blue-Blue and Purple-Blue: glow for a shorter time and more weakly than the natural shades.
- Pink and Light Red: glow much more weakly. Here the daylight colour comes first.
What should you know about Light Red, Pink and Purple-Blue?
With these three shades, the glow differs clearly from the daylight colour, or charging needs the right light.
- Light Red glows greenish in the dark. A true red afterglow is not technically possible.
- Pink glows a warm orange. Pink and Light Red also fluoresce under UV or black light; the afterglow that follows remains weaker than with the natural shades.
- Purple-Blue is excited only slightly by room lighting, depending on the lamp. Charge it with UV light, such as a UV torch, or with sunlight. In the dark it glows blue.
What are coloured glow sprays suitable for?
Coloured shades suit objects that should show a particular colour by day and also glow in the dark. They adhere to wood, metal, stone, plastic and many other surfaces. If a blue glow is what matters most, Natural Blue is the stronger choice: it is whitish by day and glows more strongly and for longer than Blue-Blue. Gold and silver shades with a green glow are under glow spray in gold & silver.
How to get more glow from coloured shades
Because tinted shades glow more weakly, the surface, the coats and the charge make the difference.
- Prime dark surfaces in white or a light colour first. On a light base the spray glows much more strongly.
- Spray several thin coats. Each additional coat makes the glow stronger and longer.
- Charge the surface directly with a bright lamp or UV light.
After a full charge, in complete darkness, the coloured shades glow for several hours – the more coats and material, the longer, but for a shorter time than the natural shades. The full spraying guide is under glow spray, the background under Afterglow explained. Not for children under 14.
