At the moment the background colors of the console messages are not fitting to the types of messages. Errors are currently having a yellow background, which could convey an impression of a warning. Warnings though are having a cyan background color, which indicates, that the message is an info block and is also straining for the eyes. To avoid this confusion and strain I would suggest to use the standard signal colors as background colors (which are already used by the icons for the messages). This would lead to the following color scheme:

error => red warning => yellow info => blue anything else => white

Therefore I attached a screenshot how it's looking now and another one showing how it would look like after the change.

Changed the colors according to the description in r6952. To check the new color scheme have a look at the test case of issue 2861.

This is one of 28 issues fixed in Firebug 1.6a12. Please try it and let us know. http://getfirebug.com/releases/firebug/1.6X.

Thanks for your report!

I have a different opinion on this.

"Error" is something which ranks much higher in the popularity of message displayed. Hence, making it look very stark would be inaccessible from readability point of view.

Info and Warning ranks way below in general statistics of FireBug usage or standard console usage and hence my point.

Thus, this point of usability with respect to popularity of usage of warn/log/error should be considered.

Did you see how it was before? Warnings were much more emphasized with the cyan color and the yellow background of the errors was less obvious. That was the reason why I changed this to more appropriat colors. Also in issue 2861 filtering by type was added to the Console Panel, which should be enough IMO for a reasonable UX. Did you have something else in mind to improve the display of console messages?
