one of the best clean, neat and corporate website can be rated to the apple website. The best thing I am always impressed by this company is its range of product, which are very creative and innovationed to match a great style a product design can get. They mix it all with a great blend of uniqueness and branding. The world is crazy about about their iMacs, iPods and other products, even if you can browse their website you can feel the touch of perfection, quality and creativity. Well to get to know about apple's website color pallete, you can take a look at the screenshot and the color pallete extracted from it. I have restricted myself to four colors.
So guys, feel free to steal this color scheme and use it in your projects.. :)
