 Why is my Rebecca Pepper crossed out in the style spin? Does that mean this color doesn't exist? No, no, no, no, no. As you know, some properties may override others according to the cascading order. Overridden properties are crossed out too, but they don't have warning icons next to them, because that's just how the cascade works. In your case, Rebecca Purple is totally valid, but the deep pink wins because its selector has higher specificity than that on the headline element. If you change your mind, you can uncheck the color to test it. I would suggest that you move the color definition to the headline. Nice. Wait.
