You've chosen a design for your website, uploaded your photos, and added pricing profiles to them. To refine your design, you can customize the buttons on your website to make them more visible and enticing to your clients or potential clients.
Under My Website / Design / Style / Buttons and controls, feel free to choose a color that you like and think would go well with your design. Keep in mind that complementary colors can be effective in making them stand out, though you probably won't want to distract from your images.
Once you've chosen a color, you can proceed to change the look of the buttons. Less rounded corners, a darker overlay, shadows - all can be customized. We've already chosen a default color that matches the rest of your design, but you have total control over small details as well, so have fun!
