The WonderFil Guide to Color Theory
Learn all about how colour theory can help your next sewing project with the WonderFil Colour Theory Guide!

Hello sewists, welcome back to another WonderFil blog! As we come into the new year with new projects on our to-do list, we thought we might chat with you about color theory. Colour theory is a large part of any design process when you’re planning your projects and can elevate your projects a lot when done properly. So, whether you’re creating a fun new quilt, crafting your own garment, or making something small this blog has something for you!

Why is color theory important

Colour theory can change the way that people look and react to your projects. A well put together color palette can be very pleasing to the eye and incite a positive reaction to those looking at your projects. If you’re making a quilt and want to add some decorative topstitching to it with heavy thread consider the color of the fabrics, and the color of the other threads you’re working with to create a beautifully curated selection of threads and fabrics. Having a good understanding of color theory can also inspire new project ideas just based on a color palette you love!

Let’s talk about the color wheel

Having an image of the basic color wheel is the easiest way to create your own color palette. We all learned at a young age the primary colors, Red, Yellow and Blue. What if you don’t want to use these three basic colors though? Luckily these colors break down into secondary and tertiary colors. The secondary colors are Orange, Green, and Violet. The secondary colors breakdown once again, only this time into six tertiary colors: Red-Orange, Yellow-Orange, Yellow-Green, Blue-Green, Blue-Violet, Red-Violet. This color wheel shows all of the possibilities for color combinations!

What kinds of color combinations are there?

There are three main color combinations that you can always rely on when choosing your color palettes, no matter how you place them on the color wheel.

Complementary colors are two colors opposite of each other on the color wheel. Because there’s typically a sharp contrast between the colors it can make your projects pop. The most commonly used examples of complementary colors is red and green!

It’s easy to come up with amazing color combinations, but what will it look like when thread and fabric interact with one another?

But, there’s a plethora of other really great complementary color combinations that you can use such as light pink and emerald green, yellow and purple!

Analogous are three colors anywhere on the wheel directly beside each other. When choosing an analogous color palette there will be one color that will dominate the palette, and the other two will work to support it as accent colors. As a result an analogous color palette can be very pleasing and in some cases even calming to the eyes. Analogous colors are perfect for when you want a monochromatic look without giving up on great color combinations.

Some examples of the perfect analogous color palette are light green and blue through a rich purple, or even just light blue through a rich royal blue and a deep purple for a regal look. And for a happy and light springy look you could combine pale blue, deep purple and lilac or even red orange, orange and yellow!

Triadic colors, or split complementary colors, are three colors evenly spaced around the color wheel, and tend to be very bright and dynamic colors. Using a triadic color palette can create contrast and harmony within your color palette, and make your project really pop.

Some great examples of these colors in action are violet, green and orange or even yellow, blue and red!

Warm vs. Cool colors

Knowing the distinction between warm and cool colors can also really help you in your decision-making process when it comes to color. And even though the distinction between warm and cool colors might seem easy, there are some colors that can fall into warm or cool categories that might shock you!

For example, some purples can fall under both warm and cool colors depending on their undertone. This also applies to greens! We’ve put together a couple of visual samples to show you exactly what we mean!

In this example we’ve pulled a cool and a warm toned purple thread. Splendor R5118 is a cool purple, and in contrast with the warm toned purple you can see that this thread has blue undertones. The warm purple thread, Splendor R1121, in comparison to the cool colored thread has obvious red undertones, creating a pleasantly warm-colored thread!

Greens can be a bit harder to differentiate between warm and cool because there’s no obvious red undertones in the warm greens, instead you have to look for a much less obvious yellow undertone. Splendor R4145 is a good example of a warm toned green, especially when contrasted against a cool toned green. Splendor R4128 is a great example of a cool toned green because of the soft blue undertone.

So how can you pair this knowledge with your sewing projects?

Now that you have all of the knowledge needed to confidently make color decisions based in color theory! Take into account the colors of the fabrics you’re working with, what the mood of the project is, if you want some nice contrasting colors or a more monochromatic palette. Spend some time and curate a color palette using color theory that feels exactly how you think the project should feel!

This quilt is a great example of using lots of warm colors with hints of cool tined purples and blues to create a visually exciting piece. Warm colors paired with a bright warm toned thread can create a very happy, energetic looking quilt! This project used our thread called Ultima™, a 40wt cotton wrapped polyester thread.

If you’re feeling inspired to create a project with rich warm tones, you can find some gorgeous fabrics from Alison Glass, some of which are featured in the quilt pictured above! You can shop her fabric bundles here:

This quilt pattern by Sew Kind is the perfect example of making use of beautiful cool colors to create a calm, and balanced color palette. This project used our thread called FabuLux™, a 40wt trilobal polyester, which creates a beautiful surface shine to the thread. The shine that FabuLux™ gives off is the perfect way to add a little bit of extra visual interest when you want a calmer and more toned down color palette.
