Sun pigment

Sunlight-activated (photochromatic) pigment

Photochromatic pigment reacts to the UV component of sunlight and changes colour. It is subtle to neutral in the shade, and brightens to yellow, violet, crimson, sky blue or brown in the sun. Just a few drops into jewellery/casting resin will create a piece of jewellery or decoration that surprises with its "in the light" effect. Also great for decorations by windows.

How it works

The pigment contains photochromic particles that switch between a colourless/faint state and a vibrantly coloured state when exposed to UV radiation. When removed from sunlight, the shade gradually returns to its original appearance.

Dosage and mixing

  • Start small: a few drops for a smaller volume of resin (the effect is pronounced).
  • Mix slowly and thoroughly to minimise bubbles and ensure the pigment is evenly dispersed.
  • Use a small amount for a translucent look; for a stronger colour change, dose carefully, drop by drop.

Where it works

  • Jewellery (pendants, earrings, rings) – a surprise effect when exposed to sunlight.
  • Decorations – coasters, curtains, smaller objects placed by windows.
  • Combination of effects – can be layered with clear zones, glitter or pearlescent (test compatibility first).

Tips for the best result

  • Darker backgrounds enhance the contrast after illumination; retains a subtle appearance in the shade.
  • Use a UV lamp or direct sunlight for a quick reaction test.
  • Plan for thinner layers for jewellery – they activate and deactivate faster.
Warning: Long-term and intense UV exposure can cause the effect to gradually fade (photochromic fatigue). Do not exceed the dosage – too much pigment can prolong curing and reduce clarity. Always test on a small sample.
