A WMS source ? Can you set the bgcolor of that service?
You could also use the transparent_color option of MapProxy to make the black background transparent, and then use bgcolor on the MapProxy WMS to make it white: <a class="moz-txt-link-freetext" href="http://mapproxy.org/docs/nightly/sources.html#image">http://mapproxy.org/docs/nightly/sources.html#image</a>
But the results are not that pretty if the source image is anti-aliased.</pre>

Thanks, Oliver. Yes, WMS.<br>
I finally set the transparent option of WMS requests of both
Mapproxy and JOSM, together with a #202020 JOSM background.
Choosing this shade of gray is a puzzle to avoid clashing with any
color of JOSM and of any transparent server.<br>
Inverting the server's colors would solve the visibility problem but
would distort the server's natural colors (yellow rivers and red
forests). In fact, it's not a matter of color but of intensity:
only the least intense tones must change in intensity.<br>
