Instead of just lightening the background, lightness curve #14
Description
Currently, we essentially fade the colors of the reverse rendering of the card graphics (to ensure contrast against the text, readability), which makes it harder to see what they are from a distance, which is a problem. We could avoid fading the lighter colors if we could find a filter in inkscape that lets us just selectively fade the dark colors. There should be such a filter. It's possible it exists as a plugin.
