Color is a very important thing to be considered when it comes to branding and identity. SEO is not the only thing thats going to get you brand identity theres lot more than that of which color is one among the very important elements. My self proclaimed teacher for my seo and online marketing learning’s  an smarty had written an excellent post regarding to color branding which is a major resource for this post. Some website colors can make you leave immediately and some sites will stick your eyes on them for their appealing color. Whenever i think of samsung my mind associate it with blue color, when i think of coca cola it associates with red color. The impact of the color in your webpage can very much affect,

1. Your brand awareness by marking your brand name into visitors mind
2. Immediate positive or negative association related to your brand color
3. your new visitors engagement and interactivity in your website
4. the tendency to make them come back and check whats going on in your website
