One of the best free customization tools on WordPress.com is the ability to upload a custom header image. Using a custom header is a great way to showcase your style and personality on your blog.
When readers visit your blog, its header is what pops out first and introduces visitors to your site and your content. That header image plays a huge part in your blog’s first impression, and now you can live preview custom header images as soon as you upload them.
Experiment by uploading header images in the Appearance → Customize → Header area. The new preview feature helps you to choose the header that best matches your site’s style and design.

Color matching for headers
If you’ve purchased the Custom Design upgrade, you can generate a color palette to match your header image with the new Match Header Image button in the Colors panel under Appearance → Customize → Colors. Keep clicking the button to see different color arrangements.
Here are a few examples showing how unique headers and color matches can vary the look of a single page:
Have fun experimenting with colors and custom headers on your blog!
