Comprising cadmium sulfide, CdS, this pigment undergoes meticulous processes to achieve its distinctive hue. Its crystalline structure and light-absorbing properties contribute to its remarkable color purity.

How to Make Cadmium Red by Mixing Colors?

Creating Cadmium Red through color mixing is a fascinating artistic endeavor that allows you to achieve this iconic hue using a combination of other pigments. It’s about understanding the color theory behind hues that have mesmerized artists for centuries. 

Materials Needed

How to Make Cadmium Red by Mixing Colors: Step-by-Step Guide

Mastering the process of creating cadmium red through color mixing, you not only gain the ability to craft this unique shade but also open up a world of creative possibilities for customizing your palette-

  • Start with a Base Red: Squeeze out a portion of your chosen red pigment onto the mixing surface. This will serve as the starting point for your cadmium-red mixture.
  • Introduce Cadmium Yellow: Using your palette knife, gradually add small increments of Cadmium Yellow to the base red. Blend thoroughly after each addition, observing the color change.
  • Adjust with White: To fine-tune the tone and intensity, introduce small amounts of white pigment. This will help control the saturation and brightness of the resulting Cadmium Red.
  • Test and Refine: Apply a small sample of your mixture onto a canvas or paper for evaluation. Compare it to a genuine Cadmium Red sample to ensure you’re on the right track. Make further adjustments if needed.
  • Finalize Your Cadmium Red: Once you’re satisfied with the shade and intensity, mix a larger batch of your Cadmium Red mixture. Store any excess in an airtight container for future use.

How to Make Cadmium Red: Traditional Method

The traditional method of creating cadmium red is a journey steeped in artistry and technique. This time-honored approach allows you to craft this captivating pigment from scratch, infusing your artwork with its warm, earthy allure. 

Gathering materials 

Each component plays a pivotal role in the process, ensuring the final pigment achieves the desired vibrancy and texture-

  • Cadmium Metal: This endeavor’s cornerstone is obtaining high-grade cadmium. Ensure its purity for optimal results in the fusion process.
  • Sulfur: Source elemental sulfur, a critical component that will undergo meticulous preparation before blending with cadmium.
  • Kiln or Furnace: Select a kiln capable of precise temperature control. This is essential for the fusion stage, where cadmium and sulfur unite to form cadmium sulfide.
  • Pestle and Mortar: These tools facilitate the initial grinding process of cadmium metal. Their use demands precision to achieve the desired texture.
  • Grinding Mill: A reliable grinding mill is indispensable for achieving the desired particle size. This step sets the stage for a smooth and consistent texture in the final pigment.

Step-by-Step Guide to Making Cadmium Red

The traditional method of creating cadmium red demands a blend of technical precision and creative intuition. Here is how to make burnt umber using the traditional method-

  • Preparing the Cadmium Metal: Start by meticulously cleaning the cadmium metal. Any impurities present can compromise the final pigment’s purity. 

Then, reduce cadmium oxide to its metallic form using a high-temperature technique.

  • Sulfur Preparation: Source high-quality elemental sulfur and refine it for optimal fusion results. Grind and sift sulfur to attain a uniform, fine texture for fusion with cadmium.
  • The Fusion Process: Control kiln temperature precisely for the fusion of cadmium and sulfur. Maintain a contaminant-free atmosphere for the purity of the resulting pigment.
  • Grinding and Milling the Pigment: Gradually grind the fused material to attain the desired particle size for texture and color intensity.

Use precise grinding techniques and monitor particle size distribution for a uniform texture.

  • Testing and Quality Control: Conduct color assessments under various lighting conditions.

Expose the pigment to simulate light and environmental conditions to assess its resistance to fading and degradation. Fine-tune the production process based on test results to ensure consistency and vibrancy.

Mixing Cadmium Red with Different Mediums: Binding Agents

Cadmium red can be mixed with various mediums, such as water, oil, and acrylics, to create different types of paint. Each medium’s binding agent brings its unique characteristics to the final artwork.

Making Cadmium Red Oil Paint

For those who prefer oil painting, combining cadmium red with linseed oil is a classic method to create oil paint. Linseed oil is a traditional binder used in oil painting to create oil paint. 

Adding a few drops of oil to the pigment

Mixing cadmium red with linseed oil requires patience and skill to achieve the perfect consistency. Artists can experiment with different ratios to find the balance that suits their painting style.

Preparing Cadmium Red Watercolor with Gum Arabic

Gum Arabic is a crucial component in creating watercolor paint and combining gum Arabic cadmium red results in watercolor with excellent flow and transparency. 

Artists can experiment with different proportions to achieve their desired effects.

Mixing Cadmium Red with Acrylic Mediums

Cadmium red can be mixed with various acrylic mediums to create a custom paint palette like flow medium, matte medium, or gel medium. Each medium affects the paint’s texture, drying time, and opacity. 

By experimenting with different mixtures, artists can unlock the full potential of cadmium red in their acrylic artworks.


  1. Can I use recycled or repurposed cadmium for pigment production?

Repurposing cadmium for pigment production is a practice fraught with potential pitfalls. While it may seem like an eco-conscious approach, it comes with inherent risks. Recycled cadmium may contain impurities or contaminants from its previous use, which can greatly affect the purity and quality of the resulting pigment. This can lead to inconsistencies in color and texture, making it unsuitable for professional artistic endeavors where precision and reliability are paramount. Therefore, it is generally advised to opt for fresh, high-grade cadmium to ensure a pigment of the highest quality.

  1. How can I achieve different shades of Cadmium Red?

Achieving a spectrum of Cadmium Red shades is an art in itself. By skillfully manipulating the proportions of primary colors, you can fine-tune the intensity and tone of the pigment. Begin with a base red pigment and gradually introduce cadmium yellow to brighten and warm the hue. To adjust the saturation or lightness, incorporate varying amounts of white pigment. This delicate interplay allows for a nuanced palette of Cadmium Red shades, each with its own unique character.

  1. Are there any health risks associated with making Cadmium Red at home in a traditional method?

Yes, there are inherent health risks in the process of creating Cadmium Red. Cadmium, a heavy metal, poses potential health hazards, especially when handled in its raw form. Direct skin contact or inhalation of cadmium dust can lead to serious health issues. It is imperative to adhere to strict safety guidelines. This includes wearing protective gear such as gloves, goggles, and a respirator, as well as working in a well-ventilated area to minimize exposure. Additionally, proper disposal of waste materials is crucial to prevent environmental contamination. Following these precautions ensures a safe and responsible approach to creating Cadmium Red at home.
