TLDR: White on white = invisible; The Colorful Spotlight fills covers -- and does not annotate -- the content. Allow for the ability to make adjustments Currently, the "Annotations" feature appears to be movie files. Those movie files offer white imagery. White imagery of white text means they are not visible. There is an exception to those, which is the Colorful Spotlight, but that has a white background in the center, so any content you want to annotate with a circle around it will be covered up. Notice the two examples in my screen capture: Colorful spotlight suggests placing a rounded circle spotlight over content, but no alpha channel (opacity) setting exists. Therefore, the spotlight blocks the content The other annotations, like "Circular Annotation," are also white, so they are not visible when placed on a white background Design ideas: * If I am right, annotations are mp4 files. Create vector-style annotations allowing line thickness, colors, opacity, etc. * Offer "color variants" of the existing annotations * Remove the white circle in the Colorful Spotlight annotation so it is in an alpha channel * Recognize that people may be sharing a background with any number of colors, not just black/dark screens with white annotations
