GOLDEN OPEN Slow-Drying Acrylic Paint Cadmium Red Medium — 59 ml Tube, Extended Blending

GOLDEN OPEN Slow-Drying Acrylics Cadmium Red Medium in a 2 fl. oz. tube is a professional, slow-drying acrylic paint that delivers rich, permanent cadmium red with extended blending time.

This slow-drying formula from GOLDEN gives artists the warmth and permanence of Cadmium Red Medium (PR108) while keeping paint workable longer on the palette and canvas. Designed to bridge the gap between fast-drying acrylics and oils, this pigment offers excellent lightfastness and semi-opaque coverage, making it a dependable choice for studio work, glazing, portraiture and plein air sessions where extended blending matters.

How does GOLDEN OPEN Cadmium Red Medium improve blending and glazing?

The OPEN formula slows surface skinning and evaporation so you can blend edges and build translucent glazes over multiple sessions. That control lets you achieve smoother colour transitions and layered depth without rushing.

• Extended working time for soft edges and subtle gradations
• Excellent for layered glazing due to its semi-opaque tinting strength
• Maintains colour stability while thinning for washes and transparencies

What are the permanence and performance characteristics of this cadmium red?

Cadmium Red Medium (PR108) in this tube is formulated for professional permanence and colour intensity. It carries an ASTM Lightfastness rating of 1, indicating excellent resistance to fading indoors under normal display conditions.

• Pigment: PR108 (concentrated cadmium sulfoselenide) for strong chroma
• ASTM Lightfastness 1 — high permanence for archival studio work
• Semi-opaque coverage that layers well with complementary colours

Can I mix this slow-drying acrylic with other paints and mediums?

Yes—GOLDEN OPEN mixes readily with standard acrylic paints and many acrylic mediums. Because it slows drying, mixing it with faster acrylics lets you tailor working time without compromising adhesion or colour.

• Mixable with faster-drying acrylics to moderate open time
• Compatible with acrylic mediums for texture, body, or gloss adjustments
• Not recommended for continuous exterior exposure; best for protected displays

How does the slow-drying nature affect studio workflow and palette management?

Slower skinning reduces waste by keeping mixed hues usable across sessions, which is especially helpful when working on multipart projects or refining a single palette over days. It supports techniques that require revisit and revision without repainting large areas.

• Preserves colour mixtures longer on the palette for multi-day projects
• Minimizes frequent remixes and colour inconsistency
• Facilitates stepwise refinements such as glazing and subtle retouching

Who is this for: GOLDEN OPEN Cadmium Red Medium 2 fl. oz. is aimed at professional and advanced artists who want the chroma and permanence of cadmium red combined with more open working time than standard acrylics. It suits portrait painters, plein air artists who need flexible drying control, printmakers and anyone who relies on extended blending and glazing without switching to oil paints.
