Amazon and Google both have custom chips. Here's what they said about their future.

Google Messages launched chat themes in late August, allowing users to personalize their conversations with custom colors and wallpapers. I've experimented with various themes and created ten that I believe are particularly appealing. These themes can be made using built-in wallpapers or personal photos.

Starting with built-in wallpapers, one of my favorites is a wavy blue lines wallpaper from the Textures folder. Paired with the third color theme, it creates a calming effect without appearing cluttered. For a space-themed wallpaper, I adore the Elephant's Trunk Nebula photo. The default color option pairs best with it, offering a rich orange with yellow accents.

Another space wallpaper I like is the Rosette Nebula, with colors that are warm and orange-yellow. Color six is the best match, providing a rich orange with yellow accents. Lastly, the second sunset wallpaper in the Sunsets folder looks great with the third color option, featuring a yellow sun against a blue sky.

From the Backdrops app, I used the Graphite Grooves wallpaper, which has a subtle design suitable for a calming chat theme. The eighth color option complements it well, creating a sleek and stealthy appearance. Another Backdrops wallpaper, Gradient Hills, transitions from dark blue to purple and pink/orange, making the blue color option a great choice.

The Stock Pixel wallpaper, reminiscent of the original Pixel and Pixel XL, is a solid choice for adding Pixel nostalgia to your chats. Any of the bluish colors would pair nicely with it, but I particularly like the green one. Lastly, the Halftone '86 wallpaper is a bit busier but works well with the eighth color option, featuring pink chat bubbles against a colorful background.
