Hey, thanks for your interest. Good question! So the processing looks for the pixel in the image with the lowest contrast to the text colour. This is a conservative approach. The reason for choosing a conservative value is that the text can appear in a different location relative to the background image depending on factors like the size of the user's screen and which font their browser chooses. I am keen to refine and need to think a smart way to do it, keeping thing accessible for as many users as possible. Hope that answers your question.
