The first thing you will notice about Codeigniter.com is the use of the color red.  The site looks overly bright, and focuses the attention right where they want it to be: at the header, with a clear explanation about the product and the most important actions right up for grabs. The use of a glassy flame for a logo made me smile.

The website is very user-friendly; there is a lot of spacing, giving it room to breath. Next to that, a lot of icons are used to create visual borders between blocks of content. The layout is neat and logical, but also pleasing to the eye.

The use of bright red and orange makes it hard to forget about the website, once you paid it a visit.
