What Two Colors Make Yellow?
If you’ve ever wondered how yellow comes into play when mixing colors, you might be surprised to learn that yellow is actually a primary color in both the RYB (Red, Yellow, Blue) color model used in art and the RGB (Red, Green, Blue) color model used in digital screens.
In the RYB color model, yellow is a primary color—meaning it cannot be created by mixing other colors together. Unlike other colors that are formed by combining two or more hues, yellow stands on its own as one of the foundational building blocks of the color spectrum.
However, if you’re experimenting with colors in a different context, such as light mixing (RGB model) or working with paint, things can get a bit more nuanced. Let’s dive deeper into what makes yellow and explore some color mixing basics!
1. Yellow as a Primary Color
In traditional color theory (often used by artists and in painting), yellow is considered one of the three primary colors, along with red and blue. These three primary colors cannot be made by mixing any other colors. Instead, they form the foundation for creating a wide range of other colors through color mixing.
- Primary Colors: Red, Yellow, Blue
- Secondary Colors: Green, Orange, Purple (these are created by mixing two primary colors)
- Tertiary Colors: A mix of primary and secondary colors
2. How Does Yellow Appear in the RGB Model?
In the RGB (Red, Green, Blue) model, which is used for screens (like your computer monitor or phone), colors are created by combining light in different intensities. Here, yellow is produced by mixing red and green light at full intensity, without any blue. When these two colors of light combine, they create the bright, vibrant hue we recognize as yellow.
- RGB for Yellow: Red + Green (No Blue)
- Additive Color Mixing: The RGB model works on the principle of additive color mixing, where combining different light colors can produce other colors.
So, in digital media or lighting, yellow comes from the combination of red and green light—not red and blue, as you might initially think.
3. Creating Yellow with Paint:
When working with paint or pigments, the rules of color mixing differ slightly because of subtractive mixing. In subtractive mixing (the color process used in painting or printing), colors are mixed by removing (or subtracting) wavelengths of light. In this case, yellow remains a primary color, so it cannot be made by mixing other colors.
However, in certain painting techniques, like watercolors or acrylics, you might lighten or alter yellow with the help of white or other light pigments. While you can’t make yellow by mixing two colors together, yellow can be blended with other colors to create a range of hues, from soft pastel yellows to vibrant oranges.
4. Common Misconception: Mixing Colors to Create Yellow
A common myth is that yellow can be created by combining red and green, which is a mistake often made when learning about color mixing. In fact, in the RYB (Red, Yellow, Blue) color model (used in painting and art), yellow cannot be made by mixing two other colors. It stands as one of the three primary colors, just as red and blue do.
In contrast, in the RGB color model (used in screens and lighting), red and green light combined can indeed create yellow, but this is specific to light mixing, not pigment mixing.
Conclusion:
So, when it comes to the question “What two colors make yellow?”, the answer is straightforward:
- In pigment (paint), yellow is a primary color and cannot be created by mixing two other colors together.
- In light (RGB model), yellow is made by combining red and green light.
Whether you’re mixing paints, working with screens, or just exploring color theory, understanding these fundamental concepts can help you grasp how color mixing works in different mediums. So next time you encounter yellow in your creative endeavors, remember it plays a unique role in color mixing—and no two colors can truly make it in the world of pigments!
