I usually have to make websites based around logos that are very colorful (4-5 colors). Let's say the colors of the logo is similar to the logos of Chrome, eBay, Joomla, MSN.
What are some of the techniques to designing around such logos especially those that are very vibrant / bright? (Putting them side-by-side makes the colors clash.)
One technique I know is to use plenty of white space and use the colors as 'accents'. Are there other guidelines? Should all the colors be used?
