I am creating a document in Adobe Illustrator CC.
I have a heading that needs to run across a section of white background and a section of navy blue background. I would like the text to take the opposite colour to the background. In other words, where the background is white, the text should be navy blue. Where the background is navy blue, the text should be white.
I've followed the instructions recommended for a similar purpose using black and white backgrounds, at How to invert text color with respect to background in Illustrator?
I can understand why this might be the case since we are using an opacity 'difference' setting, but does anyone have a solution that will allow me to invert navy blue and white depending on the background colour?
