As a child, I remember being fascinated by the colors in my art box. I could mix and match endlessly, creating endless shades of green, purple, and blue. But when I tried to make black, I always felt a tinge of disappointment. It never quite seemed to come out as pure and deep as the black in my crayons. Why was that? What colors did I need to achieve that perfect black?

It turns out, the question of “what colors do you need to make black” is more complex than it initially appears. It’s not just about mixing colors haphazardly. There’s a whole science behind understanding how colors behave when mixed together. Understanding these fundamental principles can help us create a truly satisfying black, one that’s rich, deep, and truly captivating.
Understanding the Color Wheel and Primary Colors
To grasp the concept of creating black from other colors, we must first understand the color wheel and the primary colors. The color wheel is a visual representation of the relationships between different colors. It’s organized with primary colors on the outside, secondary colors in the middle, and tertiary colors on the inside.
Primary colors are the foundational building blocks for all other colors. They cannot be created by mixing other colors. The standard primary colors are red, yellow, and blue. When mixed in specific combinations, these primary colors create secondary and tertiary colors.
Subtractive Color Mixing
Color mixing in the context of painting, printing, or other tangible mediums relies on the concept of subtractive color mixing. In this system, as you add more colors, the resulting mix becomes darker. Think of mixing paint – as you add more colors, the mixture becomes less bright and more saturated. This is because each pigment absorbs certain wavelengths of light, essentially “subtracting” them from the white light reflecting off the surface.
Subtractive Colors are the Key
To understand how to create black, we need to focus on subtractive color mixing. Subtractive color mixing is essentially the process of removing (subtracting) light from white light to create a specific colour. When we mix colors together, we are actually combining different sets of wavelengths of light. The resulting colour reflects the light that remains after the pigments have absorbed the other wavelengths.

Creating Black with Subtractive Color Mixing
Theoretically, to create a pure black through subtractive color mixing, we should mix cyan, magenta, and yellow. These colours are considered the primary colors in this system. They’re also referred to as “CMYK” (cyan, magenta, yellow, and black). Why black? Because when we add blue, plus red, plus yellow, we theoretically cancel out all of the light that is reflected, leaving us with just black. In reality, however, creating black requires more than just mixing these colors together. The quality of the pigments and their proportions play a considerable role.
The Difficulty of Creating a Pure Black
Creating a perfectly pure black is often a challenge. Even when you mix the right colors in the right proportions, the resulting shade of black may not be as deep or as rich as you want. There are a few reasons why this happens.
Firstly, pigments are never fully pure and often contain impurities that impact their appearance. Secondly, the pigments are very difficult to control. You may not be using pure colours. You may be using colours that already have black in them or other impurities. These impurities add a degree of complexity to the color mixing process.
Thirdly, black in the real world is often a mixture of different dark shades, and not purely just black. Even the darkest black pigments reflect some light. This means that we can’t completely eliminate light reflection, resulting in a slightly less pure black. Additionally, the presence of certain pigments in other colors (like a slight green tint in yellow or blue), can skew the resulting black with the slightest touch of those colours.
Tips and Expert Advice
Despite the difficulties, there are some things you can do to achieve a richer black using subtractive color mixing. Here are some tips:
- Use high-quality pigments: Higher-quality pigments are less likely to contain impurities that can affect the purity of your black. Look for pigments made from natural materials or carefully prepared synthetics.
- Experiment with different ratios: Don’t be afraid to experiment with different ratios of cyan, magenta, and yellow until you find a combination that produces the desired black. This involves a bit of trial and error and it may require altering the mix as different pigments have different densities.
- Add a touch of black: While it may seem counterintuitive, adding a small amount of black to your mixture can actually help create a deeper, more dramatic black. Remember, pre-mixed black is rarely pure and often contains other colours. Use it sparingly.
- Use a black paint as a base: Start with a base layer of black paint and then add other pigments as needed to achieve the desired shade. This is similar to layering colour in digital painting.
- Consider using a glaze: A glaze is a thin layer of transparent paint that can be applied over your existing black to create a deeper, richer hue.
These tips can be applied to various mediums, whether it’s paint, inks, or even digital media. Always experiment to find the process that works best for you.
FAQs
Q. Is it possible to create an absolute black?
No, it is not possible to create absolute black. All pigments reflect some light. However, with careful selection of pigments and techniques, you can get very, very close.
Q. What is the difference between black and white?
Black is the absence of all light. White is the presence of all light. This concept is more relevant to subtractive color mixing.
Q. Can I use a black marker or pen to make black?
Yes, you can use a black marker or pen to create black. However, these markers and pens often have a different color composition than paints or inks.
Q. Can I create black using only primary colors?
In theory, you can create black using only primary colors. However, in practice, it is difficult to achieve a pure black due to the challenges mentioned above.
What Colors Do You Need To Make Black
Conclusion
In conclusion, while creating a pure black can be tricky, it’s certainly possible through strategic color mixing and a bit of experimentation. Understanding the principles of subtractive color mixing, the color wheel, and exploring different pigments can help you achieve a truly captivating black. So, the next time you’re mixing colours, don’t shy away from trying to create that perfect black. It might just surprise you with how rich and deep it can be.
