Why Do We Love Complementary Colors?


Color choices in weaving -- choosing from the untold number of hues in the yarns and dyes available to us -- are among the most valuable decisions we make as weavers. Color can transform a well-known, often repeated weave structure and turn it into something interesting, illuminating, even heartening. 

For an example, take a look at the photo above: It's a simple turned twill on 8 shafts, woven with a hand-painted 5/2 Tencel weft on a hand-pained 60/2 silk  warp. To me, the glow of the yarns, combining an electric blue and a coppery orange, makes for a visually appealing fabric. Nothing fancy going on here, really, just a juxtaposition of complementaries.

It's amazing to me how complementary colors -- those that lie across from each other on the color wheel -- have such immense appeal to our eyes and spirits.

Nature understands this, of course.

Why are these combinations so beautiful? Science tells us it has to do with the photoreceptor cells in our eyes -- the rods and cones that interpret color for our brains. Rods can detect light and dark, while cones detect colors. And it seems that, if these receptors become overstimulated, they seek to return to normalcy. 

We all know about the after-image effect: When you stare at a bright color for a while and then look away, you will see a ghost image of its complement on the color wheel.


Stare for a few seconds at the green geese on a red background, then look away. 
You will see an after-image of geese in magenta on a blue background.

It's as if our eyes seek balance, as if a marriage of opposites is soothing to our senses. Our eyes look for harmony. At least that's my interpretation. 

So what does this mean for our weaving choices? It all depends, of course, on which technique we are using, what effects we seek and what color combinations we ourselves enjoy, as everyone's rods and cones are different. 

But if I can speak for one technique -- that of choosing warp colors for Echo threadings, where you're threading your loom in two or more alternating colors -- I've come to the conclusion that complementary colors in a warp can produce unexpected and beautiful results in the fabric. It depends greatly on the weft, of course, as it so often does. Here are a few examples, from workshops I've taught.

Most recently, Anne Benson of North Carolina chose these two colors for a workshop I'm teaching, "One Warp, Many Structures: An Exploration of Extended Parallel Threading." 


If you go back to Itten's color wheel, you'll see that these are complementaries: a cherry red and a lime green. And taken at face value, most folks would say that this is an unlikely combination, right? Well, I heartily endorsed her colors for this workshop because I've seen what happens when you start to weave. And here's what happened, using a teal-blue weft.


The fabric now has a softer, more nuanced and very lovely palette, with the chartreuse becoming turquoise and the red becoming magenta. In my view, that's because the teal weft shifts and unites the two complementaries in the warp, serving as a sort of mediator and bringing the opposing colors into harmony, visually speaking. 

Here's another endorsement for using complementary colors in your weaving. In this case, the complements are one of the warp yarns and the weft.

Sample by Sandra Schulz, 4 shafts based on "Blooming Leaf" pattern

Blue and orange working together once again, where a warm red in the warp (what I'm loosely calling orange) works to with the light blue in the weft (which looks almost textured in this photo) to make it seem to pop and glow.

And let me take this one step further, to show you a sample I wove on four shafts using four seemingly discordant colors in the warp.


This is a 4-end parallel threading on 4 shafts.

Here, the four colors in the warp are red, orange, chartreuse and turquoise: two sets of complementary colors (red/chartreuse and turquoise/orange). I'm guessing the weft is a bronze color, which is again a sort of "mediator" among the four, in a medium value and a fairly unsaturated hue.

I don't always practice what I preach, however, which is urging weavers to choose colors out of their comfort zone, understanding that the weft can make such a difference. What happens when I don't follow my own advice?

A fabric like this, which has an attractive pattern (in Echo on 16 shafts) -- but one that is hard to see because the colors are too close in hue and value. The warp colors are royal blue and aqua and the weft is black, if I recall correctly.

Nice, in my opinion, but no cigar

Right now I'm planning an inaugural piece for my new (to me) 32-shaft Megado. I've designed a 32-shaft extended-parallel-threading pattern in two warp colors.

You can't tell, but the warp colors in this drawdown are royal blue and aqua -- the same colors I used for the not-as-successful piece in the prior photo. The weft is a red/orange color, a complement to the warp colors, which makes it work. 

I originally planned to go with these two colors for my warp.


These are what you call "analogous colors," meaning that they are near each other on the color wheel. And yes, they will work for an Echo design -- but I'm thinking that, based on my recent experience, they won't create an exciting design, even when woven with a complementary color in the warp. It's a safe choice, you might say.

So I decided to take my own advice and make my warp-color choices by thinking out of the crayon box. And here's what I'm using.

Midwinter Night's Dream: How to Design 4-Color Echo


From this...

To this...

And this...

And this...

And this!

Four-color Echo seems to be at the top of every weavers "To Do" list these days -- chiefly because of the flowing lines and delightful iridescence. There are lots of drafts out there, certainly, and many gifted weavers creating patterns.

But how do they do it? And, more important, how can you do it on your own?

It's all through the magic of weaving software -- in my case, Fiberworks Silver for Mac. Here are some basic steps I've learned in preparing to teach a workshop for the New Hampshire Weavers Guild in April. 

Step 1:
Choose your yarn in 4 colors for your warp. This is not as easy as it sounds! I recommend starting with 10/2 cotton (or something similar in grist). To keep it simple, start with two colors that are analogous (next to each other) on the color wheel or close to it -- in my case, that was orange and yellow. Then move across the color wheel and choose two more analogous (or close to it) colors -- in my case, purple and blue. You'll want four colors that give you a broad chromatic range.

Step 2:
Calculate your sett, width in reed, and number of warp ends. For Echo, choose a sett that is denser than twill but less dense than double weave. So for 10/2 cotton I chose a sett of 36 epi. My warp was 400 ends, giving me a weaving width of about 11 1/6" in the reed.

Step 3:
Now for the designing. Let's work on 8 shafts, which is what I did for my samples. As always with the curves of Echo, you start with a design line, using the Freehand tool on Fiberworks. Here is a sample design line. (I am showing you a different design from the one I wove for the samples, because I don't want to give away my drafts before the workshop.)


Step 4:
Create a parallel threading. On the Warp dropdown menu, click on "Parallel Repeat." Then click on "Extended Parallel," then enter the number 4 in the box that says "Shafts Shift By." Make sure all the other boxes are unchecked, and then click "Apply." You'll get something like this.


Each warp end in the original design line now has a parallel that is four shafts above it. (Sometimes the parallel appears to bounce around. The reason: For a warp end on shaft 8, the parallel thread that is 4 shafts "above" it is on shaft 1. Because we have only 8 shafts, we have to treat shaft 1 as the "9th" shaft, just as we would with a corkscrew twill.)

Step 5: 
Create a 4-end parallel threading. Fiberworks has instructions on how to do this (which you'll find if you hover your cursor over the "Interleave" command in the drop-down menu under "Warp"). Essentially, it involves opening a second draft and cutting and pasting (really, interleaving) between two drafts. I found that a bit complicated, so I tried to do it another way. And it worked! How I did this: Starting with the parallel threading I created in the image above, I clicked once again on the "Parallel Repeat" option in the Warp dropdown menu. Like before, I clicked on "Extended Parallel" -- BUT this time I entered the number "2" in the box marked "Shafts Shift By." (And of course I made sure the other boxes were unchecked.)

Makes sense, doesn't it? For a 4-end parallel threading on 8 shafts, you'll want an interval of 2 between each warp end (interval of 2 x 4-end parallel = 8). So this is how our 4-end parallel threading looks.

Step 6:
Add your colors. For the PC version, you have to add your colors by hand. For the Mac version, you follow these steps: On the Warp dropdown menu, click on "Fill Warp Colors," then scroll all the way down in the box at the top right to select "ABCD." Four colors will appear in the boxes and, for our demonstration purposes, just click "Replace." (You can play with colors to your heart's content once you've read this tutorial.) Here's how our threading draft looks now.


Step 7:
But what does the full drawdown look like? That, dear reader, is for you to determine. From this point on, you can follow the instructions for Echo tieups and treadlings that I laid out in my blog post here (on February 17, 2018), giving you steps to begin designing your own extended parallel threading drafts. But just to give you an idea of how our demonstration drawdown might look, here's one version. (I'm using a blue weft -- and don't forget, if you're working with 10/2 cotton for your warp, you'll want to use a 20/2 cotton -- about half the grist -- for your weft. And also don't forget that your weft colors will have a big impact on the overall look of your fabric.)


It could use some tweaking for sure -- but not bad for starters. The design possibilities are endless! Thanks for reading.
