What Are Primary, Secondary, and Tertiary Colors?

In color theory, colors are categorized into three groups: primary, secondary, and tertiary. Primary colors are the foundation of all other colors. Red, yellow, and blue are the primary colors, and they cannot be created by mixing other colors. These three form the foundation for creating all other colors.

Secondary colors are formed by mixing two primary colors. For example, combining red and yellow gives you orange, while blue and yellow create green. These secondary colors fill in the next layer of the color wheel.

Tertiary colors are created by mixing a primary color with a neighboring secondary color. For example, blue mixed with green creates teal and blue combined with purple makes indigo. This process expands the color spectrum, offering more flexibility for creating custom hues in design.

Understanding these color groups provides the foundation for creating more complex shades and variations in design.

What Two Colors Make Blue

What Two Colors Make Blue?

While blue is a primary color, it can actually be produced by blending magenta and cyan in equal parts. Cyan is a greenish blue used in the CYMK palette, and magenta is purple-red. Blending cyan and magenta is how modern CYMK printers make the blue most of us are familiar with today. However, you could argue that cyan alone is already a kind of blue.

If you’re wondering how to make blue in various design settings, you should know how different models work. Understanding what two colors make blue can give you greater control when working with color in your web designs, especially when adjusting hues for specific projects.

How To Make Blue In Different Design Color Models

Blue behaves differently across various color models, each offering unique ways to manipulate the color and create different shades. Here’s how blue is treated in three major models.

RGB Color Model

In the RGB model, used primarily in digital design, blue is one of the three primary colors, along with red and green. You don’t need to mix anything to make blue in this model—it’s a base color. However, by adjusting the levels of red and green light, you can create different shades. For example, increasing the intensity of green while keeping red low can give you teal while reducing both red and green can result in darker shades like navy. Knowing how to make blue in RGB allows you to control what two colors make dark blue by tweaking light combinations.

CMYK Color Model

In the CMYK model, which is used for printing, blue is not a primary color. Instead, it’s created by mixing cyan and magenta. The proportion of these two colors determines the specific shade of blue. For example, a higher concentration of cyan produces a lighter blue, while more magenta results in a deeper, richer tone. So, when you ask what two colors make blue in CMYK, the answer lies in the balance between these two shades.

HSB (Hue, Saturation, Brightness) Model

The HSB model focuses on how colors are perceived in terms of hue, saturation, and brightness. To create blue in this model, you start by setting the hue to around 240°, which corresponds to blue on the color wheel. From there, adjusting the saturation and brightness will give you different shades of blue. Higher saturation produces more vibrant blues, while lowering the brightness gives you darker tones, which answers the question of what two colors make dark blue in the HSB model—simply adjusting brightness and saturation levels can create rich, deep blues.

What Colors Make Shades of Blue in Web Design?

Creating various shades of blue for web design involves adjusting the RGB values and using hex codes to fine-tune the color temperature. Let’s break down how you can create both warmer and cooler shades of blue by mixing specific amounts of colors.

Blue in Color Schemes

Using blue effectively in web design requires understanding how it interacts with other colors. Let’s take a look at the color schemes and how blue can be incorporated for various design effects.

Complementary Colors

  • What It Is: Complementary colors are directly opposite each other on the color wheel. For blue, the complementary color is orange.
  • Why Use It: This color scheme creates a high contrast, making elements stand out. It’s perfect for highlighting important features, such as calls to action, by drawing users’ attention quickly. The contrast makes the page visually engaging without overwhelming the user.
  • Example: AWeber uses a sky blue and black palette complemented by orange call-to-action buttons, creating a striking visual impact that emphasizes important actions

Analogous Colors

  • What It Is: Analogous colors sit next to each other on the color wheel. For blue, this includes shades like teal (blue-green) and purple (blue-violet).
  • Why Use It: This color scheme provides a harmonious and unified look. It’s more soothing than complementary schemes, making it ideal for backgrounds or sections where a relaxed, cohesive feel is needed. It’s great for designs aimed at creating a calm atmosphere.
  • Example: Florent Biffi uses a gradient of blue shades complemented by soft purples, creating a visually pleasing and cohesive design that is easy on the eyes.

Monochromatic Colors

  • What It Is: A monochromatic color scheme uses different shades, tints, and tones of a single color. For blue, this means using variations from light blue to dark blue.
  • Why Use It: Monochromatic schemes create a clean, professional look while adding depth and subtle variation. It’s ideal for minimalist designs that emphasize simplicity without losing visual interest.
  • Example: Loom utilizes a baby blue and white contrast throughout its design, maintaining a minimalist aesthetic while ensuring clarity and ease of navigation.
