Welcome to？another installment of our series on Color Theory! In the first two posts we took a closer look at the Color Wheel， and discovered the basics of Color Harmony. Today’；s post is all about how colors can play with each other， and play tricks with your color perception.
Here’；s an example of colors playing games. Take a look at the two patchwork blocks below (scroll down to learn how to make your own Contrasting Colors Patchwork Blocks just like these).farmhouse lumbar pillow
This block appears to be a dark gray square in a light gray square.
And this block appears to be？a light gray square in a dark gray square. Which of the two smaller squares in these blocks is the lightest？ And which is the darkest？
Would you believe both small squares are？exactly the same color gray？
Here’；s another one. This block has a center square that appears to be a deep， dark red.
This center square？appears to be a vibrant， glowing red.
Again， the red is the same color in both patchwork squares!
What kind of tricks are these colors playing with your eyes？ When you look at these patchwork blocks you don’；t only see the center square， but the larger view surrounding the square. It is our perception of these colors seen together， simultaneouslymothers day gifts from son， that causes the optical illusion. This illusion of colors appearing to change in juxtaposition with each other is called Simultaneous Contrast.
The term simultaneous contrast was coined by an unlikely color theorist， French chemist？Michel Eugène Chevreul？(1786-1889). Because Chevreul studied？the chemistry of natural dyes early in his career， he was appointed？Director of Dyes at the Royal Gobelins？tapestry factory in Paris. He spent many， many years experimenting with how colors interact？together， and published his findings in his 1839 masterwork on color，？The Principles of Harmony and Contrast of Colors. His book was important in first identifying the principles of simultaneous contrast， and became？influential to artists for many generations.
About a century after Chevreul’；s book was published， artist and Educator Josef Albers (1888-1976) created a？different way of learning about simultaneous contrast？while teaching at？the？Bauhaus. Albers approach was directly hands-on， urging his students to experiment with color interaction through using colored papers.？He published an overview of his methods in the influential？book？Interaction of Color， first published in 1963. Albers book explains in simple terms how？simultaneous contrast can make one color look like two (like the picture above)， or how color interaction can even make two different colors look like one. You can see the strong influence of Albers on quilters？like Heather Jones， Jacquie Gering， and Callie Works-Leary.
We can understand the basic rules about how colors play with each other (and our color perception) from both Chevreul and Albers.
Now we know that colors can interact and appear to change. This change in the appearance of color can occur in one or both colors， it can be subtle， or it can be very apparent.
Contrast of Value
The first principle of color contrasts is of value (light and dark contrast). The gray scale above shows？how we can perceive one solid， middle toned gray as light or dark depending on the background.
The same principle applies to the green stripe on a background of various blue values.
Therefore， a color will appear lighter on a dark background， and darker on a light background.
Contrast of Complements
The principle of contrasting complements is based on the high intensity relationship between complementary colors (read more about color complements here). In the above illustration， the green appears more？intense and bright on the red background？than on the gray background.
Very strong colors can also push neutral colors to appear more like their complements. The small gray square may appear？more greenish on the red background， and more reddish on the green background.
The force is strong with complementary colors! So strong that complements can make each other look more vibrant， and create the appearance of colors that aren’；t really there.
Contrast of Subtraction
In the illustration above， a blue-violet square is placed on a blue background and a violet background. The square seems to appear more violet on the blue background， and more blue on the violet background.？The larger areas of color seem to take away some of the same color from the small square.？This is what is meant by the contrast of subtraction.
Contrast of Intensity
Colors that are fully saturated (a true color with no white， black， or gray added) appear brighter and much more vibrant on a black background. Saturated colors lose some intensity and appear darker on a white background. And these colors will change again when placed on a gray background!
Want to play around with contrasting colors， or maybe test out some ideas for your next quilt？ Here’；s how to make some simple patchwork blocks like the samples above.
Blocks are 6.5″； x 6.5″；
For each block cut two rectangles from the main fabric 6.5″； x 2.5″；， two squares 2.5″； x 2.5″；， and cut from a contrasting color one 2.5″； x 2.5″； square.
Set up your sewing machine with a straight stitch needle plate and a Patchwork foot of your choice. I sew with a BERNINA 770 QE and am using the Patchwork foot #97D.
Sew the two main ？squares to each side of the contrasting color square using a 1/4″； seam. Press seams open.
Next， sew one of the main background fabric rectangles to the block with a 1/4″； seam. Press seams open.
And finally， sew the remaining main background fabric rectangle with a 1/4″； seam. Press seams open.
Sew one more block using the same center color with a different main background color.
Place the blocks side-by-side. Are your eyes playing tricks on you？ Share your blocks with us on Instagram by tagging @berninausa， @erika.mulvenna， and use #contrastingblocks in your post!

I know I have said this before, but I LOVE feathers—all kinds of feathers. This flower feather was one of the first ones I learned and just like the hook feather. It is a great beginner feather as there is no backtracking.?There is no magic fairy dust it just takes practice. The best thing to do is doodle, doodle, doodle! This will create muscle memory so when you move over to the machine your muscles know what to do.The wreath tends to be the hardest element to do because you are creating feathers in all different directions. So while you are practicing your feathers, make sure you are creating them in all different directions. This will help make your wreath easier to execute. As you can see from the picture below this feather doesn’t just shine in a wreath! And if you add a little stem in the center and some swirls on the outside, this feather can certainly take center stage on any of your quilts.
