![]() The color we see when a short wavelength of visible light was received by our eye is blue. Our brains create impressions of colors when we receive different wavelengths. These wavelengths are short, medium, and long wavelengths of the visible light spectrum. They allow us to distinguish and see different wavelengths of light. There are three types of cone cells in our eye. When it comes to color, cones play a big role. This is because rods are more sensitive to light than our cones. Rods allow us to see in the dark or dim light while cones allow us to see in daylight. There are two types of photoreceptors in our eyes called rods and cones. At the back of our eyes, some photoreceptors allow us to see colors from the light that we receive to our eyes. We, humans, have evolved with our ability to see colors. As an example, we cannot see radio waves that have a very long wavelength and are outside of the visible light spectrum. That is how we can see the world beautifully.īut as our eyes do not have cells to detect electromagnetic rays outside of the visible light spectrum, our eyes cannot see them. After detecting these wavelengths our brain gives us an impression of color for different wavelengths in the visible light spectrum. The reason why we can only see between the 380 to 700 nanometers is that our eyes only have cells to detect these wavelengths. So the visible light part of the electromagnetic field has a wavelength between 380 to 700 nanometers. Different energies of electromagnetic rays have different wavelengths. Interestingly, like most other animals with vision, humans can see a part of this electromagnetic spectrum. Electromagnetic vector created by brgfx – *ignore the purple color in the visible light in the above electromagnetic spectrum image after the violet color. Light has both electric and magnetic fields to it, just like all the rays of the electromagnetic spectrum. If you have heard of something called the electromagnetic spectrum, light is a part of that. We receive light from the sun in the daytime and light from bulbs in the nighttime. What is light and what lights can we see? When mixing purple color paints always use magenta and blue color in a 2:1 ratio for the best saturation and intensity of color. ![]() You just need to combine red and blue color lights or paints in a 1:1 ratio. You will only see a violet color when your eyes receive a single wavelength of 380 nanometers of light.īut you can mix the purple color with both light and paint colors. It is a true color that we cannot make otherwise just like red, green, and blue or primary colors. You cannot mix violet color either with light or paint colors. If it is too dark/blue for your liking, add a little more red to it.The Difference Between Teal and Turquoise in One Minute! Let’s try mixing cobalt blue and primary red! Try mixing equal parts to create a pretty deep purple. What Colors Make Purple? Let’s Make Purple! You can, however, experiment with the other blues and reds! However, it is not recommended that you use a yellow bias red and a green bias blue because you likely will end up with a muddy color. Note: my rule of thumb for determining a good red is to ask myself it it looks a little on the “pink” or “magenta” side! ![]() The best reds to make purple are alizarin crimson, quinacridone magenta and primary red. Liquitex BASICS Phthalo Blue is the Green Shade.īased on what we know about color bias, the best blues to make purple, according to that chart above, are ultramarine blue and cobalt blue. **If you are using Phthalo Blue to mix purple, I’d recommend using the “Red Shade” because that will be a warm blue compared to the “Green Shade”. *Note: cobalt is often more of a neutral blue but for the purpose of this post, I’m putting it into the warm category because it is a color that can be used to make a nice purple! Warm Blues (These are great blues to make purple with because they are closer to purple on the color wheel!): Cool Reds (These are great reds to make purple with because they are closer to purple on the color wheel!):
