My energy provider goes around bragging about how green they are. However, their invoices are using some combination of colors that prevents me to quickly print it with minimal ink.
Until now, I used to open the PDF in photoshop, grayscale and print, but that blue headers (see the sample) turns pretty dark even in grayscale/eco-mode. There are multiple of those, and there is also a blueish rectangle that is the graph of what I consumed on the past months.
I'd like a brain-dead one-trick that allow me to print those invoices (they also send on using purplish, the same tonality used in Slack) in a way that I can eventually read the text (which is black on white) but make these blue/purple rectangles go away.
I could lose the text those boxes contains, although I'd prefer to keep the labels, even if in really soft gradient. Not only that, but I also searched if it is possible to remove shapes element from a PDF, for example using an online tool, but the only I found allowed me to delete the text/content.
