If you are coding or editing the HTML or CSS of your website, you may be interested in either color names or HEX and RGB codes. Either way, before deciding on a color scheme, check with your WYSIWYG editor, not only for any built-in color schemes that you might like, but also for how much flexibility you have with colors. Some editors require coding knowledge in order to alter colors, but others allow for easy adjustment of colors
You can also find Hex codes, color palettes, and other information at color.hailpixel.com, paletton.com, or color.adobe.com/create/color-wheel. For more information on Hex codes, RGB colors, and color schemes, see Chapter 2 of Free and Easy Website Design for Museums and Historic Sites.
