54 The notmuch logo uses transparency. That can display poorly when
\r
55 inserting the image into an emacs buffer (black logo on a black
\r
56 background), so force the background colour of the image. We use a
\r
57 face (`notmuch-hello-logo-background') to represent the colour so that
\r
58 `defface' can be used to declare the different possible colours, which
\r
59 depend on whether the frame has a light or dark background.
