Usually something like this means that the CSS rules that sets the appearance of your form are being overwritten by another component of your site, like a theme or page builder.
Thanks for providing this info. I am checking the screenshots and your site, but from what I see, the colors you have selected in Forminator are properly applied to the form.
But take note that these options you shared may not be the elements you want to change their color. For example, the options you see to change the color of the Slider field, affects the numbers above and bellow the slider, not the slider itself. You can test this by temporarily changing these values to a bright color with high contrast like pure red or green, so you can see what’s actually affected by that change.
The behavior you see is that the options you have are limited because in the Appearance section of the form, at the top of the options, you select “Basic Styles” in the “Design Style” section. This option limits greatly the number of customizations you can apply to the form, because most of the styling will rely on the theme’s styling instead.
If you switch this option to “Forminator Styles”, you will have more options to change the color of the elements. Please try that and let us know how it looks.
