There is a particular quality to a truly clean, transparent yellow that no other colour can replicate. Not warm, not peachy — just pure, brilliant, slightly green-biased yellow light. Hansa Yellow Light (S3) is that colour. A single-pigment transparent yellow of legendary brightness, beloved by landscape painters, botanical artists, and glazers who need a yellow that layers without going muddy. This is a classic on any palette — and one with a story worth knowing.

What Makes This Colour Special

Hansa Yellow Light is a single-pigment colour using PY3 — Arylide Yellow G, a synthetic organic monoazo pigment. The chemistry produces one of the cleanest, most brilliant yellows available: a cool, slightly green-biased hue that glazes with extraordinary clarity. Unlike many yellows that go chalky when thinned, Hansa Yellow Light remains vivid and clean as a glaze, which is why it has been a landscape painter’s staple for decades.

The transparency is exceptional. In masstone at full strength it is a saturated, bright yellow. Thin it to a glaze and it becomes a luminous, sunlit yellow-green wash that works beautifully over underpainting. The colour bias is cooler than Hansa Yellow Medium, making it the go-to choice when you need yellow that does not pull warm — for clean greens, cool foliage, sunlit skies, and botanical yellows that sit on the green side of the spectrum.

The lightfastness picture is worth understanding clearly. GOLDEN originally rated this ASTM I (Excellent) based on the accepted pigment standard. In 2018, after their own extensive testing, they found that heavily tinted applications — particularly where a lot of Titanium White is added — showed more change than expected under accelerated ageing conditions. The masstone and moderate mixes continued to test well. GOLDEN changed the label to “Fair” and discontinued the colour in 2020, introducing Benzimidazolone Yellow Light (PY175) as the improved-lightfastness replacement. The existing stock of Hansa Yellow Light remains a genuine product of the highest GOLDEN manufacture quality — just with a more nuanced lightfastness picture than its original label suggested.

About Series Pricing

GOLDEN uses a Series 1 through 9 pricing system based purely on pigment cost and rarity. Series 1 uses the most accessible pigments. Series 9 uses the expensive, rare ones. What it does not mean is that Series 1 is lesser quality than Series 9. Every single series is made to exactly the same uncompromising standard. Hansa Yellow Light is a Series 3 colour, priced at $27.25 per 59ml tube.

Getting the Most Out of This Tube

Used transparently, this colour shines. Apply as a glaze over a lighter ground and it builds luminous yellow light layer by layer — the kind of sunny, vibrating quality that opaque yellows simply cannot deliver. For botanical painting, sunlit foliage, or warm sky glazes this is the transparent yellow that serious painters keep coming back to.

Given the lightfastness picture, the smart approach is to use it at full strength or in moderate mixes, and to minimise heavy dilution with Titanium White in work intended for long-term display. In glazes and impasto mixes it performs exactly as you would expect from a classic GOLDEN Heavy Body.

Thin with water up to around 25% for smoother applications. Beyond that, reach for GOLDEN Fluid Medium or Glazing Liquid — heavy dilution with water alone can compromise the binder over time. Need more working time? GOLDEN OPEN Medium or Retarder slows drying significantly.

A Note on Availability
