Theme Reference

This reference wiki is a community work in progress. Your contributions are welcome.

This is a help reference for Telegram Desktop themes. You can find new themes in the Desktop Themes Channel. You can also share and exchange themes with your friends by simply sending and receiving them as regular files in the Telegram client.

Applying a Theme

To apply a theme, download the theme in the Telegram Desktop client and click on it within the client window. In the Theme Preview window, click the Apply This Theme button and then the Keep Changes button.

If you downloaded the theme from an external source, upload the theme in the Telegram Desktop client (any chat; perhaps in your own chat), download it again in the client, and click on it within the client window.

You can also apply a theme by visiting Settings and clicking on Choose from file in the Chat background section. Open the .tdesktop-theme file here to load the theme. Tip: If you load a theme this way, it is reloaded each time you launch the app. This maybe helpful if you're making changes to the theme.

Creating a New Theme

To create a theme with just a color scheme, you only need a single text file with the extension .tdesktop-theme (instead of .txt). The text is a list of color constants and their defined colors.

To create a theme with a background image included you should put two files in a ZIP archive:

1. The color scheme in a text file. This file should be named colors.tdesktop-theme.
2. The background image in JPEG or PNG format. It can be named background.jpg, background.png, tiled.jpg or tiled.png. You should name it background if you'd like it not to be tiled, or tiled if you'd like it to be tiled.

After that you need to change the extension of your ZIP archive from .zip to .tdesktop-theme, so you'll have:

mytheme.tdesktop-theme (a ZIP archive)
|-colors.tdesktop-theme (a text file)
'-background.jpg (or tiled.jpg, background.png, tiled.png)

Color Constants

The standard list of color constants (shown below) define colors for user interface components of Telegram Desktop. The default colors are defined in the default theme color file.

The color of a constant is defined in hexadecimal format with RGB or RGBA notation. The A in RGBA stands for alpha, which defines the amount of transparency.

activeButtonBgOver: #00a32b; //RGB
msgStickerOverlay: #2223237f; //RGBA

A constant can reuse the color defined for another constant:

windowActiveTextFg: #15cd7d;
msgInServiceFg: windowActiveTextFg;

Beyond the standard list, custom constants can also be defined for easy reference and reuse:

COLOR_GREEN_LIGHT: #15cd7d;
windowBoldFgOver: COLOR_GREEN_LIGHT;
menuIconFgOver: COLOR_GREEN_LIGHT;
