Cool Color Palettes for Your Substack Homepage

Colors are more than decoration. They're part of your brand, and the first thing readers feel before they read a single word.

I have to tell you something first: I love experimenting with colors on my Substack. If you’ve been here for a while, you might have noticed that sometimes I change my entire color palette. It’s a game for me. And while I believe we all need the space to play and experiment, I also believe that at some point, you have to choose your colors and commit to them.

Your colors make you recognizable and memorable. For new visitors, they set the first impression, giving people an instant feel for what kind of style and energy they can expect from you.

Taste is deeply personal, so this post is not about telling you what to pick. It’s about making you pay attention to how much your colors actually matter, and giving you enough inspiration and ideas to put together a palette that feels like yours.

Let’s start with where you can actually use colors on Substack.

Pocket Mentoring is back. Starting in June, you get async strategic support to actually build your Substack, not just plan it. From finding your color palette to shaping your whole presence, I’m in your corner. Spots are limited. Sign up here.

Where colors show up on your Substack

Open your Website editor where you can change the appearance of your Substack. You’ll immediately see the color codes you already have (choose the Custom theme to access them).

Background color. This is the background of your entire page. I always recommend making this the lightest color in your palette. That’s how your text stays readable and your other colors actually pop. A lot of people like going full black with white text, and I get the appeal, but my personal take is that it’s tiring on the eyes.

Accent color. This is the color of your buttons and links, and it’s a bigger deal than it looks. Choose something that jumps out rather than blending into the background. It can match your wordmark color or complement it. On my Substack, for example, the purple accent complements the reddish tone of my wordmark rather than matching it.

Welcome page background. You can give your welcome page a different background color, which helps it feel intentional and separate from the rest.

Header background. You can change this independently too. When you do, that top bar visually pops forward and frames everything below it.

Footer. If you enable and customize your footer, you can give it its own color. I think it’s a stylish way to close out the page, and it’s where all the practical information lives, just like on a proper website.

Subscribe block. If you have one set up, you can give it a separate color too. I like making this stand out because it visually breaks up the page and draws attention exactly where you want it.

But your color choices don’t end with these settings. The rest is up to you.

Your wordmark, your logo, your cover images, the visuals inside your posts, subtitle “images”, and page breakers all need to follow the same color palette. I design all of mine in Canva.
