I'm working in InDesign and I'm unable to do anything with the Effects feature. It won't change colors when selecting multiply, darken, overlay, color burn, etc. And I've tried every color to see if I could anything to work. I'm having the same issue trying to add a shadow or gradiant. Nothing has changed when I add these elements. Any insight?
Could be that your Transparency slider in Adjust View Settings is set to the left in the display performance setting that you have set with Default View. Effects will create transparency on the spread. You will not see all the effects if the slider is set to not show transparency.
Make sure the item (Object, Stroke, Fill, Text) is set to the item that you are expecting the effect to take place. A stroke effect can easily be missed, especially if you are expecting the fill to change.
