channels.updateColor#d8aa3671 flags:# for_profile:flags.1?true channel:InputChannel color:flags.2?int background_emoji_id:flags.0?long = Updates;A peerColor constructor contains a color palette ID (id) and a custom emoji sticker » (background_emoji) to be re-colored using the colors in the palette and spread out throughout the palette, generating a background that can be used in the profile page of a user, and in other places throughout the UI, namely in in webpage preview message frames and message accent colors when quoting or replying to messages sent by a channel or user that enabled a custom message accents.
The color palettes is identified by an id (not by an RGB24 color); use help.getPeerProfileColors to obtain all color palettes (represented by help.peerColorOption constructors) that can be used in the background of a profile page, and use help.getPeerColors to obtain all color palettes that can be used in message accents.
A color palette is represented by a help.peerColorOption constructor: the palette ID is contained in color_id; the palette for light mode is contained in the colors field, the palette for dark mode is contained in the dark_colors field.
If the hidden flag is set it should not be displayed as an option to the user when choosing a palette to use in the profile page or in message accents.
The actual colors that should be used are contained either in a help.peerColorSet (returned by help.getPeerColors, containing a palette for message accents) or in a help.peerColorProfileSet (returned by help.getPeerColors containing a palette for profile pages), see the relative constructor pages for more info.
Use account.getDefaultBackgroundEmojis to obtain a list of IDs of custom emojis that can be used in a palette background.
All custom emojis in custom emoji stickersets » with text_color flag set can also be used for the same purpose.
Use account.updateColor to update the color palette of the current account's message accents and/or profile page; note that the current account must be subscribed to Telegram Premium in order to call the method.
Use channels.updateColor to update the color palette of a channel/supergroup's profile page accents, or a channel's message accent.
Note that channels/supergroups can use a message accent palette or profile palette only after reaching at least the boost level specified in the channel_min_level/group_min_level field of the help.peerColorOption constructor for the chosen palette.
Additionally, to change profile palettes, channels/supergroups must also reach at least the boost level specified in the channel_profile_bg_icon_level_min »/group_profile_bg_icon_level_min » config parameters.
The chosen message accent palette will be visible to other users in the channel.color and user.color fields; changing it will emit an updateChannel/updateUser update.
The chosen profile palettes will be visible in the user.profile_color and channel.profile_color fields; changing it will emit an updateUser update/updateChannel update.
If no palette is specified for a peer, a random color from red, orange, violet, green, cyan, blue, pink (eventually tweaked according to the client's theme) must be chosen locally as message accent palette once for every met peer.
