2303	User-specific background colours for inline diffs (to support colourblind)	kriegaex	anybody	I suffer from a slight red-green colourblindness. I rarely notice it, because I recognise most reds and greens. The light red and green in inline diff backgrounds, though, are hardly discernible for me. Well, I can change the red to a darker shade, so the brightness is different for both colours, making it easier for me to really recognise red as red and differentiate it from the light green for added lines.\r\n\r\nThe thing is that most other users do not like this and that the contrast to the darker red for changed characters within one line becomes weaker. \r\n\r\nMy question is: Is there any way I can tweak Trac into making those colours user-configurable? I would even welcome hacky ways of doing it, e.g. setting a local cookie or something. An option for changing the settings or switching a toggle in the user profile would be even nicer.\r\n\r\nI do not need theming, just a little customisation tip. It is nice that I can override CSS formatting globally, but doing it in a user-specific way is something else which does not seem to be supported out of the box. I might be wrong, though, because I am a Trac newbie.	defect	new	normal	Request-a-Hack	minor		diff, colour, CSS		0.10
