Mixing colors can be a fun and educational activity. When two primary colors, red and yellow, are mixed together in equal parts, they create the secondary color orange. Understanding color mixing is an important foundation for art, science, and even cooking! In this article, we’ll explore the details of mixing red and yellow paint or light, look at the color wheel, and summarize the key takeaways.
Mixing Red and Yellow Paint
When working with paints, mixing equal parts of red and yellow acrylic, tempera, or watercolor paint will make orange paint. The more paint you mix together, the deeper and more saturated the orange color will become. Here’s a quick overview:
– Start with equal squeezed piles, dollops, or puddles of pure red paint and pure yellow paint.
– Use a brush, stick, or folding motion to thoroughly mix the two colors together.
– The resulting paint mixture will be orange.
– Adding more red paint will make the orange lean towards red. Adding more yellow will make it lean towards yellow. But with truly equal parts, the red-yellow mix will be a pure orange.
Mixing Red and Yellow Light
Mixing colored lights works a bit differently than mixing paints. When red light and yellow light blend together, the result is still orange light. Here’s the light-mixing process:
– Start by shining a red light beam and a yellow light beam so they overlap.
– Where the two lights intersect, the color will appear orange.
– You can experiment with this using flashlights and colored cellophane filters. Overlap the beams, and observe the orange mix of the colors.
– With light, mixing more red will make the orange look redder. Mixing more yellow will make it look more yellow. But with a perfect balance, the overlap of the two light beams will produce a pure orange hue.
The Color Wheel
To understand color mixing, it helps to visualize the color wheel. This circle maps out relationships between primary, secondary, and tertiary colors. Here is a simplified color wheel showing just the primaries and secondaries:
| Red | Orange | Yellow |
| Purple | Green | |
| Blue | Purple |
On the color wheel:
– Red, yellow, and blue are primary colors.
– Orange, green, and purple are secondary colors.
– Secondary colors are made by mixing two primary colors.
Specifically, red and yellow make orange. This color relationship is easy to see on the simplified color wheel.
Primary and Secondary Color Mixing
In general, mixing primary colors produces secondary colors. Here are the combinations:
– Red + Yellow = Orange
– Yellow + Blue = Green
– Blue + Red = Purple
Mixing paint, light, pigments, dyes, and other color mediums follows these same patterns. Understand these color relationships, and you’ll be able to predictably mix any pair of primary colors.
This also works in reverse: secondary colors can be broken down into their two primary components. For example, orange paint contains both red and yellow pigments. Green light is a blend of yellow and blue light. And purple ink is composed of blue and red dyes.
Key Points and Summary
– Mixing equal parts red paint/light and yellow paint/light will produce orange paint/light.
– On the color wheel, red + yellow makes the secondary color orange.
– In general, mixing primary colors produces secondary colors:
– Red + Yellow = Orange
– Yellow + Blue = Green
– Blue + Red = Purple
– Secondary colors contain a mixture of two primary colors. Orange contains red and yellow, for example.
– Understanding primary + secondary color mixing allows you to predictively blend colors for painting, digital design, stage lighting, and more.

Science of Mixing Pigments
On a chemical level, mixing red and yellow pigments creates orange through additive color synthesis:
Red pigments absorb green and blue light, while reflecting back red. Common natural and synthetic red pigments include:
– Cadmium red (CdS + CdSe)
– Vermillion (HgS)
– Iron oxide reds (Fe2O3)
– Red ochre (Fe2O3 + clay)
– Organic reds (anthraquinone + azo dyes)
Yellow pigments absorb blue light, while reflecting red and green. Common examples include:
– Cadmium yellow (CdS)
– Limonite (FeO(OH) + clay)
– Yellow ochre (Fe2O3 + clay + silica)
– Naples yellow (Pb(SbO)2)
– Organic yellows (flavonoid, curcuminoid, azopyrazolone dyes)
When mixed together in paints or dyes, the red particles reflect red light, and the yellow particles reflect red and green light. Our eyes perceive this combination as orange. Different pigment ratios result in different orange hues.
Modern digital screen colors follow similar principles using RGB light combination. Mixing pure red and yellow light creates illuminated orange pixels. Understanding pigment and color science helps explain the basics of mixing colors.
Mixing Colors in Cooking
The concepts of color theory also apply when mixing ingredients for cooking:
Red foods include:
