Well the problem with black and red is that the contrast between the two is very weak, this makes it harder to read.
If you take a look at
Smashing Magazine (of which is one of the most popular blogs / resources) it uses a white colour scheme with red, green and grey.
Now you can use tools such as kuler.adobe.com and colorblender.com to help come up with a colour scheme, but do not undrestimate how powerful the colour white is.
White as a background colour and some complimentary colours that pop in contrast (reds, greens, blues etc), perhaps you can investigate this.
Here is the killer, and you need to remember this statement for as long as you make websites:
"You need to make your design invisible"
What this means is that is should be so well designed that the user should only ever notice the content, yes the design can look good but the point is puitting all the focus on the content. A design that is obtrusive will distract me from viewing your content, this will mean I won't click on any of your ads and you won't make any cash. Oh, and believe me, Smashing Magazine make sh*t loads of cash from advertising.
If you have a spare 5 minutes take a look at the slides of a chap called Dan Rubin, he talked about invisible designs at a developer conference earlier in the year. (
