'BoxColor' — Text box color
'yellow' (default) | character vector | cell array of character vectors | [R G B] vector | M-by-3 matrix
Use
DD= insertText(whiteImage, [100,234],'Hello World','FontSize',18,'TextColor','black','BoxColor','white');
It seems a more logical 'Default' choice would be the existing background color of the image, but I guess that's probably more difficult to ascertain...
