How to do purple in RGB?

To create the color purple in RGB (red, green, blue), you need to mix the primary colors red and blue. This is done by setting different values for the red, green, and blue components. By adjusting the ratio of red to blue, you can create different shades and tones of purple.

Understanding RGB Color Model

The RGB color model is based on the additive mixing of light. The primary colors used are red, green, and blue. When you combine red, green, and blue light together in equal amounts, they make white light. The RGB model is used for on-screen colors like those on computer monitors, TV screens, and mobile device displays.

In the RGB model, each color is represented by its mix of red, green, and blue components. Each component is assigned a value from 0 to 255, where 0 means none of that color and 255 is the maximum amount. By mixing different intensities of red, green, and blue, it’s possible to reproduce a wide range of colors.

Mixing Red and Blue for Purple

Purple is a secondary color formed by mixing the primary colors red and blue. Since there is no green component in purple, the green value is set to 0. To create different shades of purple, you adjust the amount of red and blue.

Here are some common purple colors in RGB values:

Color Red Green Blue
Vivid purple 128 0 128
Medium purple 147 0 147
Dark purple 102 0 102
Light purple 204 0 204

As you can see, the green value is 0 for all shades of purple. The red and blue values can range from 0 to 255. Equal amounts of red and blue make vivid purple. More red than blue creates a warmer, pinkish purple. More blue than red makes a cooler, bluish purple.

Other Ways to Make Purple

While combining red and blue is the most common way to make purple, there are a couple other methods you can use:

  • Mix red and magenta – Magenta has more red than blue, so this creates a warmer purple.
  • Mix blue and magenta – Magenta has more blue than red, resulting in a cooler purple.
  • Add red, blue, and green – You can make a muted purple by adding a small amount of green.

You can experiment with different ratios to create a wide spectrum of purple shades. Just remember to always set green to a low value.

Tones of Purple

Within the purple family, there are a variety of shades and tones to work with. Here are some of the most popular types of purple colors:

  • Violet – This is the pure spectral color, with equal parts red and blue.
  • Lavender – A light, soft purple with more red than blue.
  • Lilac – Also light and soft, but with more blue than lavender.
  • Mauve – A grayish purple with moderate red and blue.
  • Amethyst – A medium purple with strong red and blue mixing.
  • Mulberry – A reddish-purple, similar to a dark raspberry.
  • Plum – A red-leaning purple, named after the fruit.
  • Orchid – A light, delicate purple, inspired by the flower.

As you can see, purple takes on many personalities depending on how much red or blue is present. Play around with the RGB values to find your perfect purple!

Using Purple in Design

In design, purple can express luxury, creativity, or femininity. Light purples can create a sense of romance, nostalgia, or whimsy. Darker or brighter purples might communicate royalty, spirituality, or mystery.

Here are some ways to effectively use different shades of purple:

  • Use light purples for a feminine or whimsical brand.
  • Try medium purples to evoke creativity or imagination.
  • Go for darker purples when you want to convey luxury.
  • Mix purples with neutrals like gray or beige for an elegant look.
  • Combine purple accents with black for a gothic or moody style.
  • Partner purples with greens or blues for a natural, seasonal palette.

Consider the emotions and meanings you want to convey, and choose the appropriate purple shades for your design goals.


Creating the color purple in RGB is as easy as mixing red and blue light, while leaving green set to 0. Adjust the ratio of red to blue values to make different hues and tints of purple. From romantic lavender to regal amethyst, the purple family offers a wide spectrum of shades and tones to work with in design and digital projects.

Understanding how to create purple in RGB gives you the power to use this versatile secondary color to express exactly the mood, emotion, or meaning you want for your brand or designs.
