Purpose

Apply and customize the CometChat theme in Jetpack Compose — color schemes, typography, shapes, dark mode, and per-component style overrides using the CompositionLocal-based theme system.

Use this skill when

• Wrapping CometChat components in CometChatTheme {}
• Changing the primary color or color scheme
• Implementing dark mode support
• Customizing typography or shapes
• Accessing theme tokens in custom composables

Do not use this skill when

• Working with Kotlin Views theming (use cometchat-android-v6-kotlin-theming)
• Customizing bubble rendering (use cometchat-android-v6-compose-customization)

1. CometChatTheme Wrapper

All CometChat Compose components must be wrapped in CometChatTheme {}:

import com.cometchat.uikit.compose.theme.CometChatTheme

setContent {
    CometChatTheme {
        // CometChat components go here
        CometChatConversations()
    }
}

CometChatTheme is a composable that provides theme values via CompositionLocalProvider:

• LocalColorScheme → CometChatColorScheme
• LocalTypography → CometChatTypography
• LocalShapes → Shapes

2. Color Scheme

2.1 Default Light/Dark Schemes

import com.cometchat.uikit.compose.theme.*

// Light mode (default)
CometChatTheme(colorScheme = lightColorScheme()) {
    // ...
}

// Dark mode
CometChatTheme(colorScheme = darkColorScheme()) {
    // ...
}

// Auto based on system setting
CometChatTheme(
    colorScheme = if (isSystemInDarkTheme()) darkColorScheme() else lightColorScheme()
) {
    // ...
}

2.2 Custom Primary Color

CometChatTheme(
    colorScheme = lightColorScheme(primary = Color(0xFF6851D6))
) {
    // All extended primary colors (50-900) auto-generate from the primary
}

2.3 CometChatColorScheme Token Reference

The CometChatColorScheme class contains these token groups:

Primary Colors:

• primary — Main brand color

Extended Primary (auto-generated from primary):

• extendedPrimaryColor50 through extendedPrimaryColor900 — 10 shades blended with white (light) or black (dark)

Neutral Colors:

• neutralColor50 through neutralColor900 — 10 neutral shades

Alert Colors:

• infoColor, successColor, warningColor, errorColor, messageReadColor

Background Colors:

• backgroundColor1 (lightest) through backgroundColor4 (darkest)

Stroke/Border Colors:

• strokeColorDefault, strokeColorLight, strokeColorDark, strokeColorHighlight
• Aliases: borderColorLight, borderColorDefault, borderColorDark, borderColorHighlight

Text Colors:

• textColorPrimary, textColorSecondary, textColorTertiary, textColorDisabled, textColorWhite, textColorHighlight

Icon Tint Colors:

• iconTintPrimary, iconTintSecondary, iconTintTertiary, iconTintWhite, iconTintHighlight

Button Colors:

• primaryButtonBackgroundColor, primaryButtonIconTint, primaryButtonTextColor
• secondaryButtonBackgroundColor, secondaryButtonIconTint, secondaryButtonTextColor
• linkButtonColor, fabButtonBackgroundColor, fabButtonIconTint, whiteButtonPressed

Static Colors:

• colorWhite, colorBlack

2.4 Fully Custom Color Scheme

val customScheme = lightColorScheme(
    primary = Color(0xFF6851D6),
    neutralColor50 = Color(0xFFFAFAFA),
    neutralColor900 = Color(0xFF141414),
    errorColor = Color(0xFFFF3B30),
    successColor = Color(0xFF34C759),
    // ... override any token
)

CometChatTheme(colorScheme = customScheme) {
    // ...
}

3. Typography

// Access typography in composables
val style: TextStyle = CometChatTheme.typography.heading1Bold
val bodyStyle: TextStyle = CometChatTheme.typography.bodyRegular
val titleStyle: TextStyle = CometChatTheme.typography.titleRegular

Custom typography:

CometChatTheme(
    typography = CometChatTypography(/* custom TextStyles */)
) {
    // ...
}

4. Shapes

// Access shapes
val shapes: Shapes = CometChatTheme.shapes

// Custom shapes
CometChatTheme(
    shapes = Shapes(/* custom corner radii */)
) {
    // ...
}

5. Accessing Theme in Custom Composables

@Composable
fun MyCustomView() {
    val colors = CometChatTheme.colorScheme
    val typography = CometChatTheme.typography

    Text(
        text = "Hello",
        color = colors.textColorPrimary,
        style = typography.bodyRegular
    )

    Box(
        modifier = Modifier.background(colors.backgroundColor1)
    )
}

6. Extended Primary Color Generation

Extended primary colors are auto-generated by blending the primary color with white (light mode) or black (dark mode):

// Light mode: primary blended with white at various percentages
// extendedPrimaryColor50 = blend(primary, white, 0.96)  // lightest
// extendedPrimaryColor500 = blend(primary, white, 0.44) // mid
// extendedPrimaryColor900 = blend(primary, black, 0.08) // darkest

// Dark mode: primary blended with black at various percentages
// extendedPrimaryColor50 = blend(primary, black, 0.80)  // lightest
// extendedPrimaryColor900 = blend(primary, white, 0.11) // lightest in dark

You can override individual extended colors:

lightColorScheme(
    primary = Color(0xFF6851D6),
    extendedPrimaryColor500 = Color(0xFF9B8AE0) // manual override
)

Localization

To translate the UI, switch the active language, or override individual strings, route to the dedicated cometchat-i18n skill — the canonical cross-family localization reference. Android uses CometChatLocalize.setLocale(context, Language.Code.<lang>) / getLocale(context) (a separate method, not an init object — unlike web/RN). cometchat-i18n covers bundled languages, custom translations, and RTL.

Sound Manager — custom notification & call sounds

Sounds are a behavioral customization — driven by CometChatSoundManager, an instance class that needs a Context. The UI Kit plays the built-in cues automatically; use this to override a cue with your own raw resource. V6 package (NOT the V5 com.cometchat.chatuikit.* path):

import com.cometchat.uikit.core.resources.soundmanager.CometChatSoundManager
import com.cometchat.uikit.core.resources.soundmanager.Sound

val soundManager = CometChatSoundManager(context)

// Play a default cue — Sound enum is SCREAMING_SNAKE_CASE: INCOMING_CALL |
//   OUTGOING_CALL | INCOMING_MESSAGE | INCOMING_MESSAGE_FROM_OTHER | OUTGOING_MESSAGE
soundManager.play(Sound.INCOMING_CALL)

// Override with your own raw resource (R.raw.*)
soundManager.play(Sound.INCOMING_MESSAGE, R.raw.my_ping)

// Stop whatever is playing
soundManager.pause()

Hard rules

• ALWAYS wrap CometChat Compose components in CometChatTheme {} — components will crash or look wrong without it
• NEVER use Material MaterialTheme tokens inside CometChat components — use CometChatTheme.colorScheme / .typography / .shapes
• CometChatTheme does NOT extend MaterialTheme — they are separate theme systems
• When overriding just the primary color, extended primary colors auto-regenerate — you don't need to set all 10 shades
• lightColorScheme() and darkColorScheme() are factory functions, not data class constructors — use named parameters to override specific tokens
