Red is an IMPOSSIBLE web design color except when it isn't. There is an excellent comment at the end of this post sharing the best red websites:

I find that red can very easily become too overpowering. Even though some of these are running into that, others display the color proudly and cleverly, such as the Venkat Portfolio and Svizra.
The only design I liked used red as an accent (Project 1,000). Others just made me want to RUN away. When I started designing websites in 1999 I read a book about red, white and black as a powerful combination of design elements.
The book pointed out the power of simple lines and few colors especially when done so from the MINIMAL school of online design made so popular now by MOBILE. There are flashes of that clarity in some of these designs, but red as a base color is tricky and difficult as many of these designs prove..
If you know great red or great red, black and white designs please share and we will update. Thanks, M
