I was looking for more variety of colors other than the standard web-safe colors provided by BBedit, my preferred plain text editor for programming on my Mac. I found a pretty damn cool site that converts Pantone colors to RGB and Hexdecimal colors.
This color conversion tool allows you to convert Pantone® Spot Colors to RGB (sRGB) color values (Red/Green/Blue) and Hexadecimal color values (Hex). You can also view a Web Safe Color Palette and X11 Color Keywords with RGB, Hexadecimal and CSS Shorthand Hex color values.
It’s unfortunate that the combinations of web browsers, monitors and operating systems all treat colors differently. There’s no real way to have a uniform color palate… But the website is pretty cool nonetheless.
