I've been wanting to do these retro rectangles pattern for a while. I have one row of them on mugs for sale on Zazzle, but putting them in a pattern was my goal. I even named the different colorways ... I guess for marketing and portfolio purposes.

Here I have the colorway I named Roadside Motel. In the recoloring tool you can see on the right the different color groups I have prepared.

Next I merely switched to the two other color groups to obtain my desired colors. I did play with them a little by pressing the Random button a little until I was satisfied. On the left you can see the original colors and the colors that they changed to next to them.

My final three color ways!

Thank you for an informative and simple class, Daniela!
