Submit Button Subdued on FluentForms

Anyone else having an issue with the submit button on FluentForms used for opt-ins being subdued? Anywhere I have an opt-in form, it looks like this.

I am using Divi; verified there isn't some weird filter or anything. This one, in particular, is on a background image, but the form itself is set to clear. On another opt-in for a different purpose, I have the Fluentform background set to a solid color, but neither scenario matters. In any other form I create, the submit buttons show clearly, in full color. 🤔
