For anything beyond a few shades of gray, I need a tool and my Mac is blessed with more than my fair share of color scheme apps. The latest find is one of the easiest to use.
It’s called Spectrum and uses the standard harmony rules to create color schemes that are perfect for graphics folks who prefer precision, or those who are color blind (like me).
What I like about Spectrum is the floating palettes which display the color scheme and tools to create your own color swatches.
This is a handy and totally visually method to explore shades and tints within the palette before applying them to your design.
Even better is the option to generate color schemes from the color contained within an image.
Colors can be imported and exported as themes (CSS, .PNG, and ASE files). Spectrum gives you multiple options to preview a scheme. And, of course, there’s the mandatory color picking tool.
Also good is the ability to organize a collection of color schemes in a database. Spectrum is less than some color management apps, more than a few, but also includes an option to sync color palettes in iCloud.
