As I said in an earlier post, primary colors are not my favorite colors. And yet here I am making quilts for a primary colors challenge. When I first read about the Canadian Quilters Try-A-Triad Challenge, my first thought was how I could make my entry look like the colors were different than all the other entries.
I have recently been reading about optical illusions, including the Bezold effect and the Munker-White illusion. If you search for images based on these words, you’ll find many examples. Most of the websites have lots of advertising (which irritates me, so I’m not going to link to them!) but here’s one website that explains the effects and shows a really good example. Edited to add: here’s another great website, and there are many more optical illusions to entertain you.
I wanted to try this with the primary color fabrics, but first I experimented using Excel and the Fill Color tool. On the left, the 2 squares are the same red, although they look different depending on what color stripes are adjacent to the red. In the middle, the 2 yellow squares are the same yellow. On the right, you can see the 2 red columns are actually the same red.
After spending way too much time experimenting with Excel, I constructed a small quilt using the interweave technique. First, I made two 20″ x 20″ blocks, each with a yellow circle. I cut each block into 1″ strips and pinned them on the design wall alternating the strips from each block.
The last time I used this technique, my seams weren’t as straight as I would have liked, so this time I fused some Pellon 820 Quilter’s Grid interfacing onto the batting. The grid lines really helped me to keep my sewing lines straight.

Below is my finished quilt. I’m calling it ‘Don’t Believe Your Eyes’. The size is 18″ x 17″.
And even though these aren’t my favorite colors, while I was working on this one, I was thinking of how else I could manipulate these fabrics to look like different colors, so now I’m starting on another one!
