I use something like this. [home.att.net]
I mean by opposite the following.
Opposite of black is obviously white and it fits ok to the view, look and feel or whatever one wants to call it. It constrasts ok.
Now... if I need to know the opposite of #006600. It's invertion is #FF99FF but... as you can see it's not nice to read this last one over a 006600 background.
I don't know if there is anyway some algorythm to get the right color for 006600 or any. In order to be nice and readable.
Thanks,
You can study how they combine colors on road signs, airport signs etc. Often these combine colors for highest possible readability.
Why not have white text for your #006600 background, or some light version of green or yellow works well too.
These combinations give the best readability, highest readability first:
1. Yellow background, black text
2. Blue background, white text
I doubt it. Those combinations may be the among the most 'attention-getting' generally, and particularly in adverse weather conditions or in highly competitive visual environments (i.e. outdoor advertising), which explains their use in the circumstances you mentioned. But for readability in the sense of 'best for continuous reading' those combinations can't be best...
AFAIK, the best all-round combination for readability (again, in the sense mentioned above) is still - as it always has been in print - black text, white background. I assume this is the sense relevant to the original post as the poster seemed to be looking for the highest-contrast solution.
Having said that, given the nature of many electronic displays (especially LCDs) it's still often better to soften the harsh white a bit (as is also true in print with 'softer' colours of white paper...
