If you are a Hubspotter, you might think that Orange is THE color for your call to action. And it’s a great choice, if your primary colors are blues and greys like theirs are. However, the best way to see what color will stand out on your website design is to use the color wheel.
When I started out in graphics, I had an actual pinwheel pocket color wheel that I used to choose complementary colors. Now we have them online, here are two resources to choose your complementary color.
1. Open Photoshop and get the Hex Color Code2. Type that code in here: http://serennu.com/colour/colourcalculator.php
or you can use this cool tool here: http://colorschemedesigner.com/
