Ever needed to generate HTML color codes for web design? The HTML color wizard below will generate HEX color codes — the kind of color code used in web design — and is a great tool to help you pick out cohesive color combinations for your blog or website, especially when choosing colors for your brand identity. It’s important to have colors that follow the principles of color theory, or your website will lack a professional appeal. Of course, there are some designers that can safely stray from color theory-based selections, but only deliberately and with years of experience and a well-trained eye! As I mentioned, this is only a tool, but a great springboard for color talks with your own graphic designer or web designer.
