WhatsApp is turning up the customization features for chats by including new theme options, custom colors for chat bubbles, and a bunch of new wallpapers to choose from. A new blog post says the feature is rolling out now and will be available globally “over the coming weeks.”

There are 30 new wallpaper options to choose from — many of which are included in preset themes that will select the bubble and text colors for you. It could help personalize your chats or make it easier to remember which ones are most important to you.

The WhatsApp themes you set in your chats are only visible to you and can be applied to your channels as well. Plus, you can apply your theme across your whole experience or just the chats that are most special to you. If you prefer more granular control over how things look, you can manually set the sent and received bubbles to different colors, adjust the text colors, and make the wallpaper whatever image you’d like (as always).

Once the feature is available, you can change the theme of all your chats and channels by going to Settings > Chats > Default chat theme. But if you want to change only specific chats or channels, go to the one you want then select the chat name or triple dot menu on the top and select Chat theme from there.
