Before we get into what is coming and going, I want to clear up why they are coming and going. The main reason for the changes is to keep current and fresh. The new colors are something you've been asking for: fresh, vivid, true colors. Between the 2018-2020 In Colors and the Core colors, we have some amazing primary color choices.
Along with the color changes, Stampin' Up!® has made some changes to their ink formulas (to decrease bubbling in pads for smoother stamping) as well as the cases themselves. The new cases will be easier to open, have a tighter fit between the lid and base and be stackable. Plus you'll get an extra sticker to put inside the case so you'll see which colors you have open at a glance!
Now that we've covered the why's, let's get into the colors!
You'll notice that while Flirty Flamingo is retiring as an In Color, it is now a part of the core colors in the Brights Color Collection.
